All people have the potential to be healers. Some need to learn how to be in that healing space, but some people are naturally attuned to it and being around them just soothes the soul. It doesn't necessarily have to be sex as a way for the to heal. I once rode in a cab and afterwards realized the cabbie was a healer; his conversation with me and his whole energy touched me in such a way that I was calmer and happier when I reached my destination than I was when I got in the cab. No small feat in NYC!
So, sure, men are healers! And men can effectively heal through sex. As long as their testosterone doesn't get in the way of connecting with someone. I think connection is key in healing.
