Sex addiction! !
I dont know but since i was a lil kid i started to masturbate almost when i was 7 yo. Even if i had sex with my gf, masturbattion only can satisfied me. I can asked my GF to help be with this but i feel shy and find it weird. usually i had sex with my GF 5 times a day and i just want more ... and as i said only masturbating can satisfied me. Is that normal?
