Sex is a journey, not a destination.

Foreplay and caresses, before the process itself, are very important. Kissing, nipple licking, breast play and other parts of the business. If you can't last 15 minutes in sex, then do foreplay in 13 minutes. Men moan little in sex and hardly make any sounds when it's so sexy. Girls are turned on by the sound of a man moaning or growling with pleasure.
