Agreed with above comment.
Though I am not a "Norm"
When a person I like starts to like me back I think of a reasons why this wouldn't work out or why I don't like them.
I've never even hugged a guy in a romantic manner
Now I have nothing to avoid, but the times I did, I avoided them, even if I could be interested.
One of the problems of my avoidance is also who was interested in me, because apparently I attract more gay men than straight women o.0
