Sex/Precum

Since me and my girlfriend started having sex I no longer want to masturbate and haven't for 18 days. I've been on longer streaks. I can now get erections but it takes a while to orgasm during sex and some haste. I'm thinking that's not helping my masturbation issue. For now on I'm going to have sex less often or go slow and not go fast. As for the precum, we had sex unprotected using the withdrawal method several times now for lack of condoms which we'll no longer be doing. Had a bit of a scare (still am) I don't know and I've heard a lot of different answers from different people on other threads, but I feel like I'm replacing masturbation addiction with sex. The emotional and sexy connection between me and my gf is there but I still just want to desperately be normal like everyone else, as I have for a long time.
