Childhood friend and me....something weird is going on

[Undreamt]

Stop worrying about labels, they can come later when you know what you have ans what you want.

Just because you are straight, doesn't mean that you always have to be straight.
I had a girlfriend for two years, that doesn't prevent me from being gay now.

If you are that worried, talk about it with your friend, but if I was you, just enjoy it for what it is.
