most women I've been with don't say it outright, but all too often, I've been with one who brings up the story of how she's been with a small dick and said it couldn't work in the long term but that she'd never let on to the guy after she dumped him. although it makes me feel pretty smug, I must say it also makes me real grateful I don't have a small dick. In most cases the women who said this weren't size queens, just passing comment on size.
but nobody is immune from insecurity. I went out with one girl I really liked. after a few weeks of sex, she let on that she had been with a guy who was much larger than me. I hadn't asked her, and assumed she was telling me because she didn't like too big, but it turned out she had enjoyed sex with him. I couldn't get that out of my mind and ended up dumping her, I didn't want to feel I was being compared to someone else every time we fucked.
so small guys should know - there is always someone bigger, someone better, someone thicker, someone longer, even for endowed guys. Women might snigger once they done with you, but if you show some passion and skills, and if there's more to you than your dick, you're going to snag a woman who is worth it eventually. just keep fucking, practice makes perfect yo.
