How do I ask for sex 🙄

My fwb and I have a long history. Long story short we always wanna date but something gets in the way. More recently we established that my feelings are just stronger and I’m leaving to college so right now we can’t. Not the point though. Sis I need dick. I’m over the whole dating him thing and I just need dick. but I don’t know how to ask him! I feel like I’ve sent the same nudes, with the same poses, and I need to figure out how to just get him super horny again cause I need dick before I leave. Any tips?
