you can't really ask one person and assume there all the same. I personally like guys and girls, but there are so many variations of sexuality that you can never really classify everyone into one of these specific groups.
If you haven't already, you should talk to him about it. Just because he is into these other things doesn't mean he finds you any less attractive or that he loves you any less.
If it bothers you that he is this way, then you should let him no, you could probably work something out or if it bothers you still, it may not have been meant to be.
Either way, keep an opened mind, loving someone for there personality always comes first, not a gender.

talk to him about it. i personally like guys and girls but you cant help who you like. talk to him... ask him about it... the best way to understand one persons sexuality is to talk to them.

I am a 28 year old bisexual male who has been bisexual since my early teenage years. I can understand that this has been a huge shock for you as this is something you would provably never imagine your partner doing. I personally am not into ts or tvs neither am I into beastiallity (animal sex) However we can never fully judge a book by its cover and sometimes these things come out in the most awkward ways. I do however feel he should have been honest with you from the start about being bisexual and given you an oppertunity to either accept it or walk away if that is what you felt you needed to do. However it does make me wonder if he has been unhappy in the relationship for a period of time and that hiding behind the computer he thought you would never find out (or at least he hoped you wouldn't) He also may still be coming to terms with this himself as it can be very difficult to accept the fact that you are attracted to the same sex. I would suggest talking to him about this. Prehaps if there is a relationship counsellor in your area and this would assist you I suggest this option as they can have facilitate frank and direct discussion. However when talking to him about this matter I suggest you keep calm and collected as he also needs to be heard as well.

well I personally find the zoophillia and bestiality has nothing to do with bisexuality, however I do understand the Transvestite interest. There is something very alluring about a beautifal woman, faminine and sexy, and then finding out they have another thing I like to look at. I think it is one of those things that in general some men seem too rough and rugged, you know you kind of like the penis, but you still like the femininity of women. thats about all I can say, I don't agree with him being deceptive and not talking with you about his desires, but I understand the attraction to Tvs
