I have been staying away from porn for the passed couple weeks and I have only masturbated using my imagination. I met a girl that was into me and was willing to have sex. (Just as a little back story i have had sex wit 2 other girls before this one and I either lost my erection or couldn’t finish I believe this is either due to my porn addiction or marijuana use) The first time i was around her i was very ready to engage in intercourse. But she was on her period and made me wait. After about 4 days of rescheduling i was not masturbating in hopes to finally release my sexual urges with her.. she canceled on me again and I finally gave in and masturbated with my imagination. The next day she tells me to come and have sex. I was nervous because i felt i have just reset myself the day before and wouldn’t be able to preform. She gets me in her bed and she gives me oral and as soon as she turns around for me to penetrate I become soft... she tries to get me erect again but i was getting even more soft. I leave in embarrassment. Does this mean that have yet to reboot my sex drive ? I am yet to enjoy sex since I became active. I am 19 and i afraid i never will can someone offer any advice?
