Hey Fapstronauts, I am 22 and I have been watching porn for past 5 years and was a regular masturbater. Since the start of 2018 I have stopped PM, I have relapsed 5-6 times. I was a virgin till 2 weeks before. I and my gf planned to have sex. It was her first time also. She is 19(also a virgin). While having sex I was having trouble keeping the erection. It was even more difficult to keep the erection when we tried it for the second time(after 1st ejaculation). I was very ashamed after it. Need help on this guys. What was the reason? Performance pressure? Anxiety? Will stopping PM help in this?
