I assume the question is intended to imply that if you become a member of the opposite sex, but still maintain your attraction for the sex you're attracted to before the change, would you want to be attractive and attract members of the sex you're not interested in? For example, if you're a man, but you become a woman, but you're still attracted to women, would you want to be an attractive woman knowing that you would attract men?
I'm guessing everyone would answer yes, to be attractive, because who you attract cannot be controlled no matter what your sexual preference is. You can be a good looking straight guy and attract gay men, just as you can be a good looking straight woman and attract lesbians.
Who doesn't want to be attractive regardless?
