Hello Trixiegum
As I said before, I have not heard of anyone becoming/believing they were gay because of their bipolar. There may be other reasons he came to this conclusion. Quirky has commented on one of these. The manic part of the illness can lead people to think and do all sorts of things which when they are more rational they would be astounded to learn.
It may be the way he acted which led others to assume he was gay.The problem with this is that I do not know if gay men behave in a certain fashion which demonstrates their sexual preference. It seems on occasions that when someone acts out of character others will assume it's because they are gay. Yes I know it's unlikely and completely illogical but people do have strange ideas about mental illness in general. However he may have been asked, for whatever reason, which has made him think this may be true. It may be because he sees himself as a different person in a manic episode and that leads him to wonder about his sexual preference.
I am only guessing here, much the same as you. The best way to find out is to ask the psychiatrist when you next see him/her. Even if it is only a wild guess there is probably something that needs to be sorted out. And it may well have nothing to do with homosexuality.
Now the idea has been put in your head may I ask if this bothers you in any way? I suppose it is possible he has 'outed' himself but felt this was not a good piece of information to pass on. I'm sorry not to be more helpful on this topic. It is one out of left field.
I think you were going to have some counselling for yourself. If so it would be an ideal place to ask these questions.
