I am a male, and i am homosexual, and I can tell you from personal experience, it's just as if a straight man is attracted to some straight women, They find some attractive, and some none attractive.
The same goes for us, but there is no rule, and I personally don't think it has to do with either of them being gay or straight, It all depends on what the person finds attractive.
If i can be of any more help at all, Please, don't hestitate to ask =)
I am proud to be homosexual, and I have no problems with anyone asking about the details of that niche.
