I always think if you are around girls enough it sort of becomes second nature. For me, I always wanted sex but the problem was there wasn't too many females I couldn't trust and be friends with let alone be a fuck buddy. Eventually I caved in, and I felt really bad about it to, but at least the experience taught me something. Not too long afterwards I was able to find a person I could not only trust and be friends with but have strong feelings for and not feel like a creep.
