Stay away from the barracks whores dude, they go around to everyone's rooms trying to find someone to marry, and then guys like your roommate will wind up marrying them just for the BAH and opportunity to move off base.
Keep living your life the way YOU like to. Will partying and nailing whores increase your PFT score and, in turn, improve your cutting score which will get you promoted faster? No. Tell your doucheknuckle roommate to fuck himself, you're going to do YOU, and that's it. I take it you're early in your career, right? Now's the time to be serious and get ahead as fast as you can.
If it really bothers you, go talk to your SNCO and see about changing barracks rooms. Or, just wait until you get deployed, and get back; you'll be moved into different barracks then and get a new roommate.
