Probably when his tongue has gotten as far down the back of my throat as it can go.
First I would question the accuracy of the tipper, and the context of why tell me. Then I would scratch any plans to set him up on a date with my daughter. :)
When he says "I am gay"
Why am I tipped off? Do they think I'm gay too?
Who are these people? Who the phuck do they think they are anyway?
With some, I wouldn't know unless they told me. With others, I can tell from a mile away.
Some people keep their personal life personal and some like to flaunt it. I wish some would get the hint that I really don't care what they do in their personal life, or behind closed doors. (Gay, OR straight)
I wouldn't know. I don't "seek out" such things.
When he's holding his boyfriends hand.
Actually even after he sleeps with other guys I would probably still be questioning it, boys keep doing that for attention.
