I'm really curios about this..... I mean unless the girl has a condition as mentioned above (I know some-one with that same condition) I really don't see how that could be possible unless the guy was around 11" or extremely thick in girth. . .
. . .A lot of men out there don't seem to quite understand just how important foreplay is.... most especially if your well endowed....... if you want her to be able to accommodate you then you have to make her pussy hungry for it and the best way to do that is to work her up. Spend a good 30 minutes taking the focus away from your cock and make it about her........ then when she's begging for it gentle slide it in.
Well, I'm not freakishly endowed, just a little over 8" long and 6" around, but one girl who I dated for a short while in college could barely take more than half of me, even after cumming several times from my tongue and fingers. And every time I bottomed out in her she let me know LOUDLY how much it didn't feel good. She had had two previous lovers before, without the same problems, although she said they were quite a bit smaller than I was in the dick department. We settled on non-vaginal sex--she wouldn't try anal with me--for a bit, but we went our seperate ways after about a month. I never came from fucking with her.
A few of years ago I tried to hook up with a married neighbor of mine. She was in her late 30's, petite, and Vietnamese, with two kids (C-section). We had flirted a bit for a couple of years and finally wound up in her bedroom one afternoon while her husband was at work. I couldn't believe how tight she was, she was even pretty snug with just one finger inside, although she was sloppy wet from arousal. When we fianlly got to trying to actually fuck, she just wouldn't open up enough for me to wedge myself inside. We even tried using baby oil as a lube (she didn't have any K-Y), but it wouldn't work--quite painful and frustrating for both of us. We gave up and never tried to go at it again.
I don't know if these women had any sort of "condition," as they've had very pleasurable sex with other guys. I just think it was more of a case where vaginas, like penises, come in various sizes, and they don't always match up too well. These two experiences were the most extreme I've had, although more than a few women have prefered me not trying to burry that last inch (at least doing so really hard), which I can live with. Fortunately, most of my partners over the years have enjoyed the fact that I had a little somnething extra to offer. I'm just glad that I don't have a foot-long dick.
