**Delicate Dialogues: Genital touch – what does it need?** *Sensual Touch Lab Series for GBTQ men\** with ***Noam Raz*** **[BOOK HERE!](https://wearevillage.org/en/shop/sensual-touch/w08-2026)** Members 15 € Not members 30 € in English We will dedicate the evening to our genitals and full-body-emotional attention. Exploring delicate ways of approaching it, teasing it, connecting to its vulnerability and building the emotional safety it requires in order to communicate and become receptive. The evening will start with a somatic (Feldenkrais like) warm up, followed by partner exercises, leading eventually to a more free genital feedback exploration. Participants are encouraged to say no, or check and then say no (or yes). Nudity is optional. Resistances, shame and shyness are cherished and welcomed. **What is Sensual Touch Lab Series for GBTQ Men\*?** Sensual Touch Lab Series for GBTQ Men\* is a monthly workshop where we aim to create a space for sensual closeness and playful encounters. Embodied, somatic experiences that appreciate our full-bodied nature. Using sensuality as an approach to explore new ways of dealing with our own fears or patterns related to nudity, intimacy, and touch. We invite you to explore, communicate, and possibly expand your personal boundaries within a framework of mutual respect and consent. This opens up the opportunity to experience the power of touch, sensation, and non-verbal interpersonal connection. Each event will be a guided process, which will have a special touch depending on the theme and background of the facilitator\*, whether it be bodywork and touch, somatics and intimacy, or something else. These short workshops may include nudity, partner exercises or close physical interactions. **Benefits**: • Creates valuable shared experiences among GBTQ men\* through closeness, empathy, and connection. • Combats feelings of isolation and loneliness • Promotes self-love and acceptance of one’s body and identity • Provides a safe, judgement-free space to explore personal boundaries • Contributes to overall well-being and supports the ability to build lasting relationships • Can serve as a healthy coping mechanism and reduce the risk of substance abuse **General Information** • This format is for all queer men\* / queer masculinities interested in experiencing touch in a safe(r) setting. • Please pay attention to personal hygiene. • Bring a sheet and towel to cover cushions, mats, or massage tables. • This event will be in English. • This event is also available at a reduced member price – but not part of the two-free-monthly-events benefit. • Concession tickets upon written request to events@wearevillage.org available 🔵 **Delikate Dialoge: Was braucht genitale Berührung?** *Sensual Touch Lab Series* für GBTQ Männer\* Mit ***Noam Raz*** Mitglieder 15 € Nicht Mitglieder 30 € Auf Englisch Wir werden den Abend unseren Genitalien und der ganzheitlich-emotionalen Aufmerksamkeit widmen. Wir werden zarte Wege erkunden, um uns ihnen zu nähern, sie zu necken, ihre Verletzlichkeit zu spüren und die emotionale Sicherheit aufzubauen, die sie benötigen, um zu kommunizieren und empfänglich zu werden. Der Abend beginnt mit einem somatischen (Feldenkrais-ähnlichen) Aufwärmen, gefolgt von Partnerübungen, die schließlich zu einer freieren Erforschung des genitalen Feedbacks führen. Die Teilnehmer\*innen werden ermutigt, „Nein“ zu sagen oder zu prüfen und dann „Nein“ (oder „Ja“) zu sagen. Nacktheit ist optional. Widerstände, Scham und Schüchternheit sind willkommen und werden geschätzt. **Was ist Sensual Touch Lab Series for GBTQ Männer\*?** Sensual Touch Lab Series für GBTQ Männer\* ist ein monatlicher Workshop, bei dem wir einen Raum für sinnliche Nähe und spielerische Begegnungen schaffen möchten. Verkörperte, somatische Erfahrungen, die unsere Gesamtkörperlichkeit wertschätzen. Sinnlichkeit als Zugang, neue Wege im Umgang mit unseren eigenen Ängsten oder Mustern in Bezug auf Nacktheit, Intimität und Berührung erkunden. Wir laden dich ein, deine persönlichen Grenzen in einem Rahmen gegenseitigen Respekts und Einvernehmens zu erforschen, zu kommunizieren und gegebenenfalls zu erweitern. Dabei eröffnet sich die Möglichkeit, die Kraft von Berührung, Empfindung und nonverbaler, zwischenmenschlicher Bezogenheit zu erfahren.

❗️To RSVP for event, please drop a message to the host ❗️ Come join us for a gentle yet powerful **Seitai group practice** — a space where silence, breath, and spontaneous movement meet. This is a **donation-based event**, so you’re free to contribute what feels right (usually 5–10€). ✨ **What is Seitai?** Seitai (整体) is a Japanese practice that helps you reconnect with your body’s innate intelligence. Through subtle awareness and guided techniques, you’ll be invited to: * **Listen deeply** to your body through *Yuki* (a meditative, hands-on practice of sensing and following the breath). * **Release hidden tension** with *Katsugen* — allowing involuntary, spontaneous movements to arise naturally. * **Find balance** in stillness and movement, letting your body recalibrate itself in surprising ways. Seitai is not about control or forcing; it’s about giving voice to the movements your body has been waiting to express. Sometimes this brings ease, clarity, and lightness. Sometimes it stirs up dizziness, discomfort, or emotions. Every experience is valid — and you are always free to pause or leave at any time. 🌌 **Why join?** * Discover a practice that many find deeply transformative. * Create space for release, renewal, and vitality. * Explore in community, whether you’re a curious first-timer or already familiar with Seitai. 👕 **Practical details** * Wear comfortable clothes. * Bring openness and curiosity. * Watchers are welcome — you can simply observe, or dive into active practice. * The session is guided, but the real teacher is your own body. ✨ Learn more: 🎥 Watch a short video: [https://youtu.be/KF7agFE1zss?si=6UhmjwaIAfBo-_Op](https://youtu.be/KF7agFE1zss?si=6UhmjwaIAfBo-_Op) 📖 Read more about Seitai: [https://seitaibarcelona.com/what-is-seitai/](https://seitaibarcelona.com/what-is-seitai/) Everyone is welcome, whether you are completely new or already familiar with Seitai. Bring comfortable clothes and an open mind. 💰 *This event is donation-based, supporting the space and allowing us to keep offering it. Private one-to-one sessions are also available at an affordable price.* 🌿 **Step into silence, breath, and spontaneous movement — your body knows the way.**

Chitta Walks is for people whose days move fast, while the mind never fully lands. Thoughts keep looping even when nothing is urgent. The body moves, but attention is elsewhere. Over time, this disconnect drains clarity and ease. This walk is a simple reset. We meet in Berlin’s Tiergarten and walk at a gentle pace. Parts of the walk are in silence, with light guidance and a few short prompts. The walk itself is the practice, bringing body and mind back into the same moment. No apps. No performance. Just a clear space to slow down and notice what is happening. If you want to slow down without withdrawing from life, join a Chitta Walk. ✨ **What to expect (approx. 90 minutes):** * A short arrival and orientation * A guided silent walk (phones off, no conversation) * One concise science-based impulse on attention or stress * Optional reflection in pairs or small groups * A simple takeaway or experiment for daily life 🚶**Who this is for:** * Professionals, creatives, and people in transition. * People who feel mentally busy and want more clarity and balance. * Those curious about mindfulness, but grounded and practical. * Anyone comfortable with silence and gentle self observation. 🔔 **Practical notes:** * Duration: 60-90 minutes * Wear comfortable shoes and weather-appropriate clothing * No prior experience needed * Group size is limited to keep the space quiet and focused 🧭 **Facilitator:** My name is Partha Sarathi, you can call me PS. I have lived in Berlin for over 12 years. With a background in physics and materials science, my interest in mindfulness grew through personal experience with stress and health challenges. I facilitate the space and structure of the walk, inviting shared exploration rather than instruction. 🤔 **Why Chitta Walks?** Chitta is a Sanskrit word referring to the mind or field of awareness, used here in a practical, non-religious sense. Chitta Walks is about noticing how the mind works by slowing down and walking together. Mindful walking makes thought patterns visible in real time, while moving and sensing in the world. The name points to a simple capacity: noticing what is happening in the mind without immediately trying to fix, judge, or optimize it. 🌿 **Possible effects:** A calmer nervous system. Clearer attention. A felt sense of being more present in your body. Subtle insights into how your mind reacts under everyday conditions. A quieter, more grounded way of moving through the city. **Come as you are. Walk. Notice. Leave with a little more space inside.**

Bringt gute Laune, schönes Wetter und Interesse mit. Wir treffen uns je nach Tour an unterschiedlichen Orten. Am 1. April 2018 um 15 Uhr gehts los am Eingang zur Akademie der Künste am Pariser Platz neben dem Brandenburger Tor.

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
