I know that it has been talked about in other threads, but I think it applies in this thread as well. There are so many Bi women in the lifestyle, and it is so accepted, but the reverse is so... "taboo" in a way that I know bi men in the scene (myself included for a long time) that hesitated to even bring up that fact that they are open to a little soft bi play. Of course the reason is buried in the whole "macho male psyche" thing (along with a whole list of other related misconceptions and fears, but it still amazes me that in a lifestyle that is all about open feelings and breaking "taboo's", that this part of sexuality still hold the stigma it does in the community.
On a side note, being a bi man, I don’t get into watching two men together (at least I don’t seek it out), but I love to watch two women together.
Diversity, it makes the world go round!
