How long does sex last for you?

My fiancé and I have great sex but the longest it lasts is like 10/15 min sometimes shorter. I don't climax from intercourse assuming it's because of the length and not having enough time to get there but I get tingles and everything.. he usually takes care of me before hand so I'm not deprived and like I said it's GREAT sex but how long does it last for everyone else?
