Its the awkward situation where you ask yourself, ok you want to transition to remove the male (or the female in the case of FTM) part of you and become female (or again the opposite if you are FTM).
And you ask yourself, well, are you planning to neeeeeeeever have sex ever again?
I want my sex drive brought under control. In other words, I want to be the one saying when, not that damned thing.
But, if I were to be given that wonder of wonderful opportunities, to wake one day, and not have any male parts, to wake up and be a naked female when I got in the tub and have nothing to look at other than naked female parts, well, I'd still ideally like to have soooooome bit of sex life still.
So the obvious, ok you transition, you are now equipped with the right gear, who do you wish to play with in bed. I mean you won't be what you were before in as much as gear is concerned. You will still be 'you' but, now you get to maybe enjoy being you correctly too.
Myself, I have a great deal of hate for males. I think I shall never long for a day when I can be of any use to a man regardless of what my body looks like. But that's me. One has to wonder, ok, you made the switch you got your wish, what are you planning to do with your new freedom?
I have friends, I think they actually desperately want to be properly equipped females, and they actually DO want a man.
Is that going to make them homosexual? Tough question. A woman in a female body having sex with a male in a male body is having hetero sex according to some view points I suppose. Me, I think I will always be a lesbian in some fashion. But right now, I am sure most think I am just a messed up hetero male. I'm not a man though, I just have the parts. Well for now. I have hopes and dreams though.
I have a friend that messages me occasionally on Facebook. Get in the kitchen woman and make me a sammich!!

I find it comfortingly amusing.
