When we tuck our cocks away into our shorts/pants whatever, to which side do you hang? Left or right? Which Thigh gets the privilege of having your cock rubbing against it all day?

I stand corrected, to which side do you dress your cock when putting it away, Left, Right, Tucked down the middle or dressed up the centre.

My girlfriend is a seamstress. The term for which their cock hangs is DRESS. They dress to the right or the left. She said some guys wear a thin spot in the fabric of the side they dress.
Not a problem for me though.

Because I am right handed maybe more to the right.

I'm right handed but "put it away" to the left.

I.n left but stroke with ang to the right.

To the right. Have heard for years that most go to the left but I have no idea if that's true.

Quite right, your girlfriend. I learned that little nugget - aha -of information buying my first - and to date only - coat and tails.
