So I mostly watched through the videos, it really doesn't touch on anything about adults. If I remember right it said, that adults should create spaces where they were non-sexually affectionate, and accepting. I remember something about round benches were people sit in a circle and hug. The methods she writes about are pretty extreme, but they sound like the opposite extreme to your childhood.
Accepting yourself enough to have an affectionate relationship, would do the same thing. You eventually feel accepted enough, and become more confident. Make affection your goal for a while, and get to know girls before things get too dramatic. Every girl you fall for seems perfect, because you project yourself into the things you don't know about them. That is a really short lived phenomenon.
You don't have to listen to me, but a relationship would help you grow, and make you feel better. Relationship advice is way easier to give, than attention.
