My boyfriend and I have been having sex for a while now, and we've been intimate in other ways beforehand as well. He seems to enjoy sex, hand jobs, and oral sex equal amounts, but he just doesn't have the control over ejaculation during sex as he does other times. He sometimes lasts 45 minutes, but sometimes 2 minutes in he looses control. He's getting frustrated with this, and as much as I would like to say I'm not, I am too.

Has anyone else had experiences like this? Any explanation as to why it's happening? Any solutions that don't involve drugs?

PS. please don't say "get a new guy" or "zomg, sex before marriage?! Heathens!!!"
We're both 18, and I know this sounds weird, but he doesn't masturbate (literally, I think he has masturbated less than 20 times in his life).

Also, it's not like we're "getting it on" way too often. We'll do it maybe once or twice a week.
He normally has complete control over the moment he ejaculates, and since he really enjoys it, he can last those 45 minutes. (Once he got pissed at a girlfriend and wouldn't cum for a for an hour and a half while she was giving him oral , lol!)

u re young. it is perfectly normal. i would be more bothere with that one which lasts 45 min. why does it take him so long? 45 min is not normal for a young guy.
