What gets you horny to submit to sucking cock? Would you suck a stranger's cock out of the blue?

I've sucked off a number of men in bathrooms once I'd seen their cock. He'd say, "You like what you see?", I'd reply "Yes I do, may I suck on it for you?' 15 minutes later after swallowing his load we depart the bathroom.

 

All it takes for me to want to suck a cock is to think about it or see a guy naked. Never done it with a complete stranger. I want to know them some first. Guess I'm just too worried about picking up a disease. If I would ever give my wife something she would kill me.

 

Now I know what you mean you don’t want to give your wife a sexual disease.
