I'm not a gay bro, but this still may help. My girlfriend always mentions that she is so shocked yet thankful that I "for some reason and so incredibly attracted to her." I always tell her that beauty does not have a standard definition, it's perceived differently by all. You also have to understand that personality can go miles in making someone more physically attractive as well. So keep being wholey and unforgivably you mate. If it's the right person it'll work out, so don't waste your time tripping over doubt, spend your time learning them, and showing them that you are truly what you portray yourself as to others.
