Hm-m-m-m... well... are crossdressing & bisexuality mental issues? I'm certainly no expert with regard to what is & is not in the DSM. But I don't believe bisexuality is listed there. On the other hand, there is a diagnosis in the DSM, I believe, for what is termed Transvestic Disorder which involves crossdressing. Here's a link to a brief description of the disorder from PsychCentral's archives:

On the other hand, I would be willing to wager there are a lot of individuals who crossdress who would argue heartily that crossdressing is in no way a mental issue. So, perhaps what it comes down to is whether or not you are comfortable doing what you're doing. If you are, then perhaps it's not a mental issue... at least not for you. However, if it's causing you to experience such emotions as guilt & / or shame, or causing you to have anxiety, then perhaps yes it is? I don't really know. But that's what occurs to me. There may, of course, also be legal ramifications to what you're doing, depending on the laws where you live. But that's a whole 'nother discussion.
