My guy friend wants to become a man so he can get paid and get laid?

This really sounds like a bad idea. I don't know about your friend but there are other ways of living than getting laid. And just because you can doesn't mean that your confidence will go up. Tell him to try to find leadership opportunities that will offer him chances to build up his confidence among closed groups, where it might be easier for him to relax. Don't let him waste his Bachelor's degree!
