I can’t seem to cum inside my girlfriend after hours of fucking, the friction hurts my penis and doesn’t feel good at all. I have no problem doing it by myself, 1-2 minutes will do however with my girlfriend I can literally go forever. Iv never cumed inside her and lie about doing so
It sounds like you have desensitized yourself down there. Leave it alone for a while and the sensitivity will start coming back. You're too used to your hand.
I can definitely relate, i had a very strong psychological block about it with any woman I was with. It felt like it was somewhere I should not ejaculate in.
I was and am back in that same boat. It's PMO, plain and simple. A few years back, I went a long stretch without PMO on a family holiday where we were all sharing the same bedroom for two weeks. My only MO time would have been in the shower and that wasn't discrete enough. Well, by the time we got back from holidays and my wife was up for some fun, I was probably about 21 days of no MO. We had sex and I didn't have any problems with delay. I am struggling with this again, mostly because in my mind, I can't orgasm without M'ing and fantasizing about all those dirty fantasies. It's going to take some time to heal. Just be really, really patient and don't give up.
If it hurts then stop. I’m surprised that vaginal juices didn’t help reduce the friction. Maybe add lube then try again.
