So being the type of guy that I am;

-a gamer at heart, but likes to go hiking, bike riding, swimming and camping
-socially awkward
- not confident in myself in the slightest

How would I determine if I'm better off in a relationship or a friends with benefits situation? Every relationship I've been in has failed, I'm usually never given the information as to why it fails other than they lost interest in me. The only times I've had females seem close to me is when it's like a one night stand situation, we are still friends and occasionally we will hook back up here and there. But they are never interested in a relationship, though I've already had experience in both fields, I'm lost as to which would be better for me. I feel like if I choose one or the other on a whim rather than some thing like this I'll just end up hurting myself.
