Shell225: In my opinion, size matters. 25% of the female population can orgasm vaginally. Rest assured that without the appropriate friction that doesnt happen. So if one is looking for that in their sexual relationships then yes a good fit does matter to them.
We all joke about throwing a cheerio down a hall, and landing a chopper in the grand canyon. Just as guys dont appreciate 'sloppy' in a partner, Im sure that some ladies dont appreciate 'small' either.
There are incredibly skillful lovers out there, who can do amazing things. But for everyone the goal post is different. For some its achieving orgasm, for others its achieving simulatious orgasm, and for others its achieving orgasm during intercourse.
If penis size (or vagina size) inhibits that, then clearly one partner is going to feel frustrated over the long term. Just as libidos need to match, and sexual wants, so does the fit.
