How often do you see your fuck buddy?

I (F23) recently started seeing a guy (M24) we went on a date and hooked up. I’ve seen him two times after which mainly consisted of sex and sleeping over once was at his the other time was at my place. It seems that we have a sexual based situation going on which I’m totally here for I’m just wondering how often we should be initiating hookups? How often do you if you have one see someone you just have sex with? I don’t want to see clingy in any way and we both have initiated a hangout outside of the date we went on. It’s been about 2 1/2 weeks since we’ve met.
