Yeah, sure. I think you should be allowed to do what you want, or feel like.
Although if you plan to stay a woman, then when you "see" someone, make sure to tell them your actually a man on the first date, if you don't, that's just cruel.
Although people are very closed minded.
If you want just a fling, or to be banged or something, then you don't tell them.
I think it's great you want a sex change (Actually not, I don't like it when people do, but I think the world should be more liberal, so I'm supportive of you).
