Casual sex

So this guy has been really into me for a while now, and he’s cool, i have great conversations with him but I’m not exactly attracted to him. For a while he’s been asking if i wanted to have sex with him or at least allow him to go down on me but I’ve been like eh i don’t know because I’m not used to doing stuff like that casually. Lately though I’ve been super horny and i kinda just wanna do it. Lol

What thoughts do you guys have on casual sex? I need help 😅
