Is it gay to be attracted/intimate with Trannies?

I had not really thought about it in terms of gay/straight when thinking about being attracted/intimate with Transgender women, but it is a valid question, even if I struggle to be able to answer it.

If you were to ask me if I am gay, I would without hesitation say no, absolutely not, I am not attracted to men, period, end of story.

So, how do I explain my attraction to and my even being married to a Trans women? I am not sure, I know that I am not interested in men, that is easy, I do not find men attractive and I would not want to be intimate with a man, but I am intimate with a Trans women and I have been attracted to pre-op Trans women for a long time now.

I do know that I am attracted to women, I am attracted to breasts, soft skin, long hair, nice butts, femininity, in fact, Trans women who have not had breast augmentation surgery are not attractive to me, a women needs breasts and if a Trans women does not have breast (in the form of implants), I am not attracted to them.

The "penis" which I guess is the part that determines "gay" as it pertain to this question is hard to explain, but even there, I am not sure it is the penis exclusively that turns me on as much as the juxtaposition of beautiful feminine body and then a penis. I am turned on by women (of all types) who undergo plastic surgery, the before and afters to me are a major turn and one that has stood the test of time, in a sense part of my attraction to Trans women is wow that beautiful female I am looking at started off way different and through surgery is now gorgeous.

However, I would be lying if I said that Trans women's penes are not sexually arousing to me, because there is something oddly femine about a Trans women's penis.

In fact, I thought that looking at my wife's penis would be a major turn on for the rest of our lives and somehow her having a penis was a flash in the pan with regards to being turned on, as the years have progressed, her penis is just there, I honestly do not even notice anymore in as far as wow that is hot, she has a dick like I used to, it is now a days there is my beautiful sexy wife.

I do not have much of an explanation for that, other than to say, living with someone is not the same as being sexually turned on by a concept or image.
