Quickie...?

Ok so my husband and I have been married for about 7 months and our wedding night was our first time. Our sex life has come a LONGGGGG way in 7 months (like, we didn't have sex on our honeymoon just because I was in so much pain every time we tried because he was so big). Anyways, got THAT part figured out and now it's just about stamina. Mh husband has ridiculous stamina so we're having sex for like 1 1/2 hours EVERY time and we're really exhausted every time. I know this is a petty thing to ask about: but how can we reduce that time? Our frequency would skyrocket if we could master how to have a quickie... Any tips???
