Now, as for myself, I find that my nipples are extremely tender and erogenous. When a woman touches or licks my nipples I get a raging hard-on. And I've known one or two women who, when I focused my attention on their nipples, could have tremendous orgasms.
The truth, I think, is that any part of our bodies can be erogenous--ears and earlobes, the nape of the neck, the small of the back, the navel, behind the knee... and OMG our toes. I love sucking toes and I love to have mine sucked as well.... In the end it's all about giving and pleasuring and, sometimes, love.
Your body is a temple. Worship it and hope to have others that will do the same ;- )
