How? I'm a semi newbie to sex, lost my virginity five years ago but I've never gone beyond one night stands with any girl until now (I think, we've only had sex once so far). Masturbating and being used to quick easy orgasms has made it hard for me to maintain a full erection during intercourse, I just seem to have a tough time feeling anything while doing it. Is this normal for beginners? I usually hear about guys busting too fast when they start having sex, but the problem is at the opposite end for me
