The girls at RPI are like girls at any other school; there are just fewer of them with respect to the guys. RPI has a 72 males for every 28 females (last I checked). Given this, the girls will have plenty of other guys to ‘hook up with’.
That being said, I don’t know your boyfriend. I hope he can be faithful and control himself. If he wants to cheat, he probably could. Hopefully, though, he would turn down any ladies who made a move on him. Best of luck!
