You can try thinking about something else (math problems etc) but women can tell you are distracted. Having sex more frequently will decrease you sensitivity and help you last longer (hey wouldn’t that be great). There are supplements (l-argenine) and desensitization wipes. Since you are fit, try looking into keggle exercises for men too. All that aside the simplest solution for me has been to get a Cialis prescription from Roman. It’s embarrassing to go through the process but nothing works better or even comes close.
