Just one time

Gay isn't an all or nothing thing like commenters are making it out to be. It is on a continuum. On one end is all the way Gay, and not attracted to the opposite sex at all. And at the other end is not Gay at all, and only are attracted to the opposite sex.
And then there are 100 points in between. Some can be mostly over to one end or the other. And some can be near the center.
A full on Gay person likes hugging, kissing, smelling, etc. a person of the same sex.
Someone mostly at the heterosexual end might like the excitement of a cock, but no interest in the guy who has it. Doesn't want to hug or kiss or anything. Just finds cocks interesting.
Sexual attraction isn't 0% or 100% most of the time.

Well -- maybe you have a point about me being gay. I'm the 76 year old married cock sucker. I go to bed at night thinking of sucking cock. I wake up each morning thinking of sucking cock. I have a virgin ass, and think I'd like to have it fucked. Time and time again. I have my cock in my hand... stroking off thinking of sucking your cock. Do you really think I might be gay? Tell the truth, now.

If you have no interest in pussy then maybe you are gay but like the guys say, it is just a label

It doesn't matter if you've straight, Bi, or gay; life doesn't need labels. If you enjoy it and are not hurting others... just do it. Suck cock. That's how I started three years ago --- sucking just one cock. I loved it, still do, and suck cock every chance I get. Yes-- I am married and I am 75 years old... still in love with cock. Just do it and -- enjoy sucking cock.
