i'm cris i am 25 years old and until now i was at 121 days of nofap. I started because i meet a transexual girl and she did me a blo*Jo* and i touched the dì*k i dont know why. After that i was really scared to be gay and i had sex with other two girls. when i go out with a new girls i had pied so i was terrible sad, i was scared again to be gay and so on, i have started to watch porno and Mo to say myself that im not gay. i saw then this community and i understand that Porno caused this thing, like fetish and so on...when i started i was no scared to be gay but i had a lot of flatline. a day on the beach around 40 days i had an erection watching a girl, it was amazing because i really liked her!. Meanwhile i had a lot of urgences, so on 55 days i had sex with this girl that i really didnt like because, i had some problem at first with erection and PE but in that days i had sex with her 5 days. i had sex again with her on 69 days and 76 days( here i had PE again)After that i understand and thanks to NoFap that i want a relationship and i dont like casual sex. i had a lot of benefies during this trip
-stronger, more muscle, girls attraction,no eye bags but a lot flatline like i didnt like girls anymore.
