Not sure what's more exciting... someone else who enjoys her cds rubbed or someone who actually knows what a cds really is! A friend of mine from NSW called it her "floaty place" My wife prefers hers rubbed by grinding. Some women prefer it hammered deep as long as you avoid the cervix.
This is a more specific question related to penis size, but it's different because it's more specific to the thread topic. I hope I'll get some feedback. Are penises 4-5 inches in length able to stimulate the posterior and anterior fornix areas of a a vagina? Can a change in position during intercourse correct this problem if they do have difficulties? How does certain girths impact stimulation of those areas? And also how many nerve endings are really there in the fornix areas? Science says not much, but what do you women say? Are those spots exceptions to sensitivity when you get way back there?
If your penis is of average length, say 6", it always ends up in the posterior fornix. In missionary position the underside of the penis ie the frenulum part which connects the foreskin usually ends up in the posterior fornix and it stimulates that area. There is no special sensation in this region. The front of the glans presses against the mouth of uterine cervix which my wife always say it give some sensation deep down.
I consider myself as an average male. My penis reaches 6" when fully erect but I am not sure how long it reaches once it is inside my wife and about to climax.
