Female Perception of Penis Size

From a very, very long forum discussion:

…

I’m a 21 year old gay male, and I was linked to this topic by my ex boyfriend, who is bisexual and has dated several women in the past couple years. First off, my penis is uncircumcised and about 8.8 inches in length when fully erect, and my girth is about 5.5” or so [yes, somewhat thin considering the length], and my ex is circumcised and about 7.1 inches long.

Now, talking to one of his recent girlfriends before they had sex, she had told me in private that she preferred guys that were at least 8 inches in length. However, my ex-boyfriend told me that when they made love, she had apparent discomfort accepting his length despite how well lubricated she was and the amount of foreplay they engaged in. After hearing this, I spoke to her about sizes again, and she confirmed that she found his dick to be a bit large [not too large, but large enough to cause a few problems], despite the fact that his girth is only about 5.1”. I asked her why she insisted on 8 inches then, and she basically said that she had never actually measured any of her previous lovers [which seemed to be many], and that she probably didn’t exactly have a good grasp on what 8 inches actually was. I won’t go into details or explain what led to it, but just out of her curiosity’s sake, we arranged a session for me to get erect and allow her to measure me. I am almost an inch above her preferred “8 inches”, but when she saw my erection she was rather shocked, and said that she thought mine was huge. I asked her to *guess* my size, and she guessed 10 inches. After that I let her measure it, and the ruler showed about 8.4”-8.5” in length [it wasn’t a full erection, because I guess I can’t keep an erection with no real stimulation around since she was female]. …
