So, there was a thread recently saying men do everything in order to get laid. I disagree with this statement, but its correlated to another idea I do believe.

Validation comes in different forms and different intensities. Many things men do can validate them. However, sex is the largest, and most prominent (ultimate) source of validation for men. It is the truest, purest form of a man being validated for his masculinity and attractiveness. Nothing matches a girl getting naked for you and wanting you to have sex with her.

For example, I have a lot of guy friends that are pre-med, in med school, or in grad school for math. Many of them that are virgins express that having no sexual experience hurts them and makes them feel worthless. They feel good about their achievements and getting into med school etc. But when they step into a social outing they are very intimidated.

Now, this doesn't mean you need tons of flings and a high partner count. My view is that you just need to feel that you are sexually satisfied according to your own desires. CMV.
