Only dated men before...

I had only dated men before I dated this married couple. And now my current partner is transgender (ftm no hormone replacement therapy yet) and was wondering if anyone has been in a similar position where they don’t think they will date men again. I don’t know dating a man doesn’t appeal to me. I have a very high sex drive and having sex with a man doesn’t appeal to me right now even. Like if things weren’t to work out with my current partner I’d date a woman.
