There are different erogenous zones on a man. These include ears, scrotum, nipples, skin, neck, inner thighs, etc. As humans, we are all different, and different things work for us, however, if I should suggest the most erogenous zone on a man, it would be the nipples, but mind you, not every man would feel good when you touch their nipples. It can be hurtful for some, so know your man’s body.
