I don't claim to speak for all cock suckers but what I'm about to reveal isn't going to come as a surprise to those who have given this subject any thought at all. Married cock suckers, in general have a guilt complex! That's right. If you think about it why would a normal, healthy, married man actively seek out men to "service"? Something is rotten in Denmark.
Ok, maybe late in life they discover they are "bi"....really? How? Why?
Something is not right somewhere. Wife no longer has sexual desire. Failure at work. Something makes a man get down on his knees and suck a cock. That something is self loathing. He is punishing himself for sins real or imagined. By becoming servile he is submitting himself to a superior. Accepting his lower station in life. Becoming good at something, even if it is being a cock sucker.
Now that you know the obvious you can help your cock sucker achieve a level of subservience that will make him happy! You do want a contented cock sucker don't you?
First, while he has a mouth full of your cock praise him. Praise his talents but use the most demeaning language you can muster. He's not your friend right now. He's in full cock slut mode and if he just works harder on giving you a great blow-job you know you are on the right track.
