you don't need shit like that OP, all you need to do is be yourself and be confident and tell her you want to fuck. of course you also have to hit the gym for a while first until you're not ugly and working out is even more fun than sex imo. remember: an orgasm only lasts a few seconds but a 3 hour workout session feels good the whole time. it's like a slow burn of pleasure. you might just get addicted to working out and no longer even want a gf
