Not worrying about it will help. Nothing like stress and anxiety to trigger all kinds of aggravating things.

Take the pressure off and just enjoy sex. Orgasms happen because sex feels so damn good! If they occur before you want them to, enjoy it...rest and catch your breath...and get ready for the next round!

Complete surrender should not just come at moments in which one faces overwhelming odds, but in the calm when it seems one is personally in complete control of one's life.
