So I've spoken to a few guys, and the conversation always starts out normal. Just generally getting to know each other, but some how they always turn it to sex. It makes me uncomfortable because it's always out of the blue. They also tend to ask really personal questions, and I don't feel comfortable sharing things like that with a person I've only just started talking too. I ask them to stop or slow down but they never do. How do I handle this situation, and why are some guys like this?
