gay

I am I gay? Bisexual? Sometimes there is this drive in me to hug guys, show them how I appreciate what they just did for me, no token of love or maybe it is? Where is the boundary? What makes you gay? What defines love? Is love the craving to touch, the mere mutual understanding or isn't it moreover the longing for a person to be there? Is close friendship between two guys is essence love stigmatized by society?
