Why is that I don't see posts from transitioned FtM women agonizing about whether they might or might not be interested in males. Pre-op and post-op whatever their desire was before sexually is the same after. (Although the labels change)
After a transition they are women. At that point it is absolutely no issue about crossdressing, they have transitioned, they now have alignment between their inner feeling and their exterior. I am sure that I have never heard of a transitioned person for fun putting on the clothing of the former gender just to explore a different sexuality.
Some transwomen like women, some like men, some like both.
That doesn't change if they wear a prom gown or a pair of overalls.
Just because some of us get a charge (me included) from our dressing just implies that we are more on the CD side of the spectrum than TG. What we do under the influence of the pink fog is still a reflection of who we are.
