I certainly am! Not that it doesn't happen, but honestly, I have never heard a woman say that she would have a problem with a man being bi. (Unfortunately, I have only ever hear and bi-hate coming from within the LGBT community.)

As far as relationships go, if a boyfriend of mine told me he was bi, I would see that as a major positive. I am very sure that my long-term ex-boyfriend is bi (neither of us realized we were at the time). He would often get hit-on by men, and it never bothered either of us. It wasn't necessarily a turn-on either, it was just a non-issue.

I tend to be attracted to men without hyper-masculine personalities, and find that men often like that my personality is not hyper-feminine (personality and appearance can also be very different here.) In my experience, these qualities are tend to be more common among bi people, who are often less rigid about gender norms. It's one reason why I view a bi partner as a plus.

On a side note, I would also say that's it's a misconception that women are far less turned-on by gay men than men are by gay women. I think the big difference is that porn, in general, is made for men (gay or straight). Even my fairly conservative mother has told me than when she was in college in rural Iowa, the girls in her dorm would pass around erotica and romance novels, the majority being about gay men. She said the same thing happened to her in grad school. The Penthouse letters had become popular and the ones that she and her female friends enjoyed the most were the gay male stories. I noticed the same thing at a chain bookstore I used to frequent, the gay romance novels were primarily purchased by women. These were usually older women, I would assume because that most younger women are using the internet. I know when I have come across erotic literature that is written by, and primarily for women, there is no shortage of stories about gay men.
