Now I'm at college and live in a small dorm room. My roommate always goes to sleep after me. Is there any place I could masturbate, like in the shower?
A popular technique for college students is to get in bed under the covers when your roommate is out (and you don't expect him back for a while); that way you can freely masturbate, and if he comes back you can quickly cover yourself and look like you were just lying in bed. If you keep a book handy it will look like you were reading. Of course, if you're the honest type you can just say, "I was masturbating – do you mind leaving again for a few minutes?" Other possibilities are masturbating in a bathroom stall or, yes, the shower – although some guys don't like to do it standing up. (And it wastes water!)
