Just guessing...you are about right. But, there is Viagara which will prolong it
(believe it or not plus make it bigger and harder before ejaculation (WOW).... along with desensitizing cream to make it last a lot longer (maybe twice to three times longer), or a condom to numb the sensation, or self-gratification some time before sex to make the second time take longer, using a stop and start technique, a combination of these and even a little mind control.....and, other ideas from posters. So..... there is plenty of help for a man to satisfy and keep up with a woman who wants to orgasm as she should..
