Frankly no.
For one, i'm not homosexual.
Secondly, I don't have the qualities that I would look for in a significant other, and if I HAD those qualities I wouldn't need to have any sort of relationship. If I dated myself, i'd be constantly butting heads with me...Dunno really how to explain it honestly...Just wouldn't work out.
I am me, I need to be with someone other than me. A separate person who is different, but I can still relate too and ask for advice/help I couldn't give myself.
