HELP! S/He is more EXPERIENCED! To which I say:

Asked and answered in the original article, above.
In addition, many fellas operate under the misguided misconception that the way to a climax is from lots and lots of stroking and thrusting. WRONG. This is the why of all the fooling around and making out beforehand. He should be at the brink of an orgasm before entering. If he then loses his erection then it is more likely than not that it is nerves. The fix is quite literally to stop worrying. How you respond to this happening is critically important. Being supportive and helping to rebuild his erection are next in line.
Even though you have previous experience, what might help is the exercise described in orange print in this article:

> what can he do to try to maintain his erection and what could i do to help him keep it or get it back and over come this problem?
What can help to maintain his erection is for you to exercise your Kegel muscles and clamp down when he is stroking. If he loses his erection, just pause and rebuild it as described in the opening article.
Please look at the list or helpful, informative, how-to articles in the Index and read all or at least those of interest to the two of you.
If you have additional questions or concerns please do not hesitate to ask.
