I really need help with this:

I’m 19 and not really confident with girls whatsoever. This past dating experience I didn’t make a move until like the 7th date, and I feel like I was more physically, she would’ve been more into to me. But I wasn’t.

It’s just not getting physical. It’s approaching and attracting women. Telling them I like them or whatever.

I feel like I need to be more of a man. Any books?
