Let’s limit the less clever jokes and comments, please, I need the straight dope.
hypothetical situation:
There is a guy (we’ll call him Richard) in an exclusive relationship with an girl (we’ll call her Petite). When they have sex, Richard claims that his penis feels “bruised” afterwards (for about 24 hours) and Petite is usually in some post-coital pain as well. This is not rough and tumble sex they claim, just the calm, soft type. Petite says she is somewhat unsatisfied by their sex life, mostly because it hurts when Richard goes all the way in (because it feels like he “rams against her cervix”), because the duration of their sex is not very long (because Richard fits so tightly and sensation is heightened for him), also because she sometimes bleeds from lacerations due to ripped skin caused by stretching. Maybe she could do exercises to increase her size? Or perhaps there is a procedure to make him smaller? This otherwise very happy couple just wants to improve this part of their relationship and asked me to ask the teeming millions for their boundless knowledge.
No good surgery exists that is fail proof, the risks in all plastic surgery on the penis include loss of sensitivity and impotens - wouldn’t do it.
You have two problems here; girth and length.
On the length issue there is only one way, technique. Try to go more careful at it and only perform partial penetration. Avoid positions that separate the legs of the girls so much that it is easy to ‘venture all the way’ with you hips and take extra care when penetrating from behind, since some of these positions push the cervix back and in effect this makes the vagina slightly more shallow. It’s not so much how soft or hard you go at it as how much you control depth of penetration. It takes practice and isn’t universal since depth of the vagina will vary from woman to woman.
As to the girth problem. Two solutions. Extend foreplay and make sure that the vaginal muscle is well dilated before penetration. Always use lubricant.
Most people think of a massive endowment as a blessing, that’s because they haven’t suffered the downsides. In fact really large penises are quite rare and the old joke about parking and male capacity to judge how much 9 inches is has much validity. In fact the average erect penis is 14 cm (5 1/2’), meanwhile male members of the species on average answer around 17 cm (6 2/3’’), anything up to 23 cm (9’’) is ‘normal’.
I don’t have the girth averages in my head and I don’t have anywhere to look it up off the cuff like this.
I don’t have the average depth of an adult vagina either, but IIRC it is in the area of 17 cm (6 2/3’’).
Of course I answered this question from a male perspective… that’s not because I am a chauvinist (not only any way).
Seriously: In truth the problem is really up to the guy to solve, independent of whether the problem is an unusually narrow and shallow vagina or the reverse.
Four to five inches is to the tip of the cervix. The Vagina doesn’t stop dead at the cervix. A simple exploration by the careful use of a finger will confirm that the vagina continues a bit past the cervix. That’s why positions from behind will be more precarious since this pushes the cervix back and further into the vagina, which tends to get the whole machinery confounded should an unusual length or shallowness of apparatus be involved. Further the depth Cece give is form the beginning of the vaginal muscle, this is preceded by the inner labia, which in effect have to be counted as part of the depth for the purposes of geometry of the flesh mambo exercises.
Why not use a position where he will not penetrate so far? Or is this just too easy and you are looking for something complicated?
A position I enjoy is to have the woman lie, facing down, legs together, and enter from behind. Depth of penetration is much reduced to the point where the penis will easily come out if you are not careful.
As a practical metter, you can use some sort of pad at the base of his penis to prevent too-deep penetration. Sort of like a washer, or a gasket. I think such things are even sold in sex-aid stores, but you ought to be able to construct one easily enough. Use really soft polymers, though.
Cal Meacham is right–he could make little “donuts” out of foam rubber or some other soft-yet-firm material. This will decrease the length that can enter the vagina, but still allow him to thrust and feel resistance at the base.
As for his partner, she needs lots of lubrication to prevent tearing. If sex has been painful in the past, it may be difficult for her to fully relax (which exacerbates the situation). I prescribe wine, lots of foreplay, and a nice bottle of astroglide.
Heck, and here I was considering jumping into the lawsuit game by suing Trojan for not being able to roll those nodders all the way down–damaging to my self esteem, don’t you know–and here I see some other poor bastard has to put swing-rings on his rig just so he doesn’t damage the goods. Aristotle would be pleased, I think.
While I do not dispute Sparc’s explanation, it has always been my understanding that the vagina does in fact end at the cervix, with the area beyond being a kids-only zone known as the uterus. Quibbling differences, really, considering the size of the problem at hand…
No doubt does the vagina end where the cervix is and beyond that it’s ‘no fathers allowed’. However, the uterus is at an angle to the vagina and the cervix follows the angular degree of the lower uterus. The actual tip of the cervix opens into the wall of the vagina. Above the cervix there is continued cavity that is about an inch long as this diagram of the female reproductive organs shows. The site is German, but the graph speaks pretty much for itself.
