Yesterday I called my girlfriend at home, we were going to have sex but I didn't get an erection I really have no idea what actually happened to me, we both were unexperienced and virgin, because I have no idea how to insert my penis, and main problem was my penis because I was not getting hard properly, we tried oral sex it did not work and my penis started getting hard but as soon as I tried to insert I lost my erection, I wasted two condoms and I lost my respect in my eyes. I past I used to watch porn and masturbate atleaast twice a week. I do not know what to do and I hope you will find solution of my problem.
