我覺得如果是很年輕時巳有行淫的習慣,多數人到了成年期也是早洩的 ---- what an untrue statement!!
Not mentioned here is who's your partner, are you too nervous, too excited with her?
The more foreplay you have with her, the less you think about coming too soon.
Try out different positions, don't be in 1 position for too long, 30 seconds or more,
or as soon as you feel you're coming, pull out, rest for few seconds, then proceed with a different position.
Find a position that fits you, that is, you feel less sensation but she feels the most sensation.
That way, she definitely has her orgasm before yours.
Definitely helps to have the rubber on, try that also to protect yourself.
