Interesting question. But here is a question that I'm left wondering: what makes some men so incredibly bad? Other than a man being too small to physically satisfy a woman, what is it about his sexual technique that bothers you or turns you off? Lack of rhythym? No oral skills or even finger skills? Just a general lack of foreplay of any kind? What makes some men good lovers and others terrible?
I've only ever been with one woman who I would say was bad in bed, and her problem was a lack of enthusiasm. She was what men call a dead fish. It's not any fun when you don't get any kind of response back. This girl was just too insecure in her own sexuality to let go, and her issues were beyond me. Other than that, I've never really come across the issue.
