The Effing Foundation promotes sexuality education and artistic expression of sexuality, which can include many different types of projects. This can be an organization which does ongoing, sex-positive work, or it can be an individual or group of individuals doing a specific event or project.
You could propose to host a conference, workshop, or other type of event; write or edit a book (fiction/non-fiction/comics/poetry/collection/zine/...); put on a play or storytelling event; make a film or short video series; do a photo shoot; create a podcast or vlog; make a game (videogame/boardgame/RPG/LARP); build an art installation; or create a website; to name just a few ideas.
The exact medium you use is less important to us than that your project is 1) artistic and/or educational in some way; 2) grounded in your own identity and experiences; and 3) sex-positive (and that your sex-positivity includes being respectful of people with marginalized identities). If you aren't sure what "sex-positive" means, check out "What I Mean When I Say I'm Sex-Positive" by Cliff Pervocracy and "10 Things Sex-Positivity Is Not" by Miri Mogilevsky.
We are also more likely to fund projects that have few other options for grant funding or government support.
