Even if I'm not interested in a relationship or sexuality or whatever, I'm still often guilty of that, yes. Getting to know someone takes effort, and being attractive tips the risk/reward counter toward the "reward" side for some reason.

Perhaps, you are overthinking the whole idea of befriending. Many people are shy and have great conversations with people. However, it isn't easy to decide from a one-time event to go outside of the event to do other things with someone.
I also believe that how you feel about yourself shows to others. If you change how you view yourself, others will see you differently as well. Best of luck!
