I thought Mr premature ejaculation was the presdient of Paraguay..?
Anyway,moving on,,,
Its not something i have ever suffered with. I put it down to one of my girlfriends in my youth who to some extent trained me to fuck. She would get all moody if i didnt fuck her long and hard and if i shot my load too soon, she would get all moody.
It was hell but someone had to do it !
I guess i gradually learned to psychologically train and physically control myself. Part of it is controlling the mind, the thought patterns in your brain. You can ride the waves of pleasure and the experience but build a barrier in your mind that stands in the way of the tipping point where you lose control and shoot.
You can also learn to control your PC muscles,,when you are fucking a girl or being sucked/wanked, and that barrier in your mind, the wall, is starting to crumble, you can simply squeeze off your pc muscles and most times, the feeling of impending ejaculation will subside. Sometimes you might have to pause your activity,let it subside then continue.
As a bonus, if you are inside a girl and you squeeze off your pc muscles, your cock gets harder, the helmet more defined and she feels it
Im not sure pills are a good cure.
