I remember a girlfriend telling me enthusiastically that my soft cock was much bigger than her previous boyfriend's cock was when hard. They had a bad breakup, so I assumed that her comment was tinged with revenge. One night after we had managed to perform an elaborate Kama Sutra position, I mentioned that her previous boyfriend could not have penetrated her in that position.
She agreed, but went on to say that there were advantages to short cocks. I asked for examples, expecting her to say that deep throating was much easier. No, something else. She explained that due to his short cock he fucked like a rabbit, delivering many quick, short strokes like a jack hammer, which made her orgasm quickly; in contrast, a long cock necessarily made for longer, slower strokes. She explained how his pubic mound was always tightly pressed against hers, whereas longer cocks resulted in a somewhat "distant" fucking. Interesting.
Another girlfriend went crazy over an older gentleman's short cock before my astounded eyes, which I detailed here
