I have been hooking up with this girl and the sex feels amazing yet I can't seem to cum. I don't masturbate very much anymore and don't use death grip! I did think I had performance anxiety but I don't go limp, I just stay hard and can keep fucking for however Iong i like. She has tried jerking me ogg, blowing me, but can't seem to cum yet I can totally get myself off in like 10-15 min what do I do?!? I need to fix this problem!
