A masculine gender identity for queer people of colour — young, masc-presenting, often assigned female at birth, defining their own lane outside the white butch/femme binary.

aftercare
General
Aftercare is the attention partners give each other once a scene wraps: blankets, water, cuddles, quiet, reassuring words, a check-in. Intense play floods the body with adrenaline and endorphins, and the comedown can hit hard — aftercare is how you land safely. It's not optional fluff; it's a core part of doing kink responsibly, and it's the main defence against sub drop. What it looks like is negotiated like everything else — some want to be held, some want space and a snack.
after-party
General
A continuation party held after the main event or club closes, usually for a tighter crew.
