When you see the discussion on FB you really have to wonder how much of people's lives they leave open to interpretation?
It mostly sounds like "am I gay if I have sexual intercourse with other men"? The next thing you know you've got a debate about "tip depth" and "top or bottom" and the "amount of men in the room". Etc. Etc.
Somebody needs to take a definitive and objective stand on the matter of what stock is, and stop trying to give eachother a reassuring reach-around supporting their individual definitions and agendas. FWIW, it is okay to be non-stock in the same way it is okay to admitting to being gay. Just be honest with yourself and others around you.
