Erection for almost an hour: what should we do?

asks:
My boyfriend is 22 this year and he has had one sexual partner before me, I am 21 and he is the first person I've ever had a sexual relationship with. We've been having sex for almost a year and we've been together for about two years. I was wondering whether it is normal for a guy to be able to have an erection that lasts for 40 minutes (at least) to almost an hour (sometimes more) in bed?...
