sex buddy

I'm in my mid 20s in school and I'm in a relationship with my bf of 3 yrs that is both stale and not satisfying. we haven't had sex in months.. I started hanging out with this guy a couple months now and although we have mind blowing sex and his cunnilingus is on point I dont feel like I'm being completely satisfied as we don't do it often. I'm just looking for someone who can be available for me sexually on a schedule 1 to 2 times a week at least. how can I tell him my needs without scaring him away into thinking I want more or that I'm getting too attached? I just don't wanna throw my pussy around to Tom, Dick, and Harry but instead have a one Chuck to plow it
