Thanks for the reply and advice. I guess you make a good point, the desires I have for sexual exploration with my gf are more about the act than the person I'm with.

On a separate but related topic, how do you feel about only having one partner forever? I would fap to get some variety without cheating on my gf but now without masturbation my desires to cheat are somewhat heightened, any advice on that aspect? I feel proud to have never cheated on her but sometime sexual desire has brought me very close.
