Susan,,, at the start of having sex, I usually slip it in gently because I always hit the cervix. But after a while the cervix seems to dissapear and I am home free. So that humping away full force doesnt seem to be a problem.

Question is........ what happens to the cervix.... does it get pushed to the side, and out of the way ??? or does it get pushed in deeper by my thrusting. My lady friend is a pitite woman, but seems to handle me quiet nicely.

You point out one of the major reasons guys should start out slow and begin with foreplay, foreplay, and more foreplay.

The vagina elongates as it gets excited. The more excited a woman gets the longer and wider her vagina becomes. It lubricates and is able to contract and that is what makes sex feel so good.
