On a tissue, obviously. Sometimes on my torso.
As I believe, the women must completely trust the man at first. It's just what they need. Later on, when the girl is more experienced with being dominated and loves it no matter what, she can do it with any guy I suppose.
I do get horny while seeing a girl sucking cock. I am purely straight, but there is something about sucking cock.. Sometimes I wonder how would that feel, but not sure if I would try that on given opportunity.
