Yes! I had actually been considering posting a topic like this a few days ago. haha.
I am a gay man, but before I realized what I am or that it was possible, I basically sulked around and refused to do anything to my appearance that would automatically scream 'girl' or even just look feminine. Since I've come out, I think I've actually been talking in a slightly higher pitch than I used to, I'm okay with sitting around in public sewing little rabbit plushies, and I've even brought homemade cookies to school on a My Little Pony plate. Not to mention that I'm okay with wearing bright purple skinny jeans and a t-shirt that's not baggy (even tight, sometimes, but only when I have my binder on).
I haven't started medically transitioning yet, but I'm getting doctor information tomorrow. I've always been able to, if not pass as male, then at least be so ambiguous that nobody used any pronouns in regard to me unless they were specifically told what I was. Now that I've accepted that it is possible for me to still be transsexual even though I'm gay, I think I've become more comfortable with expressing my feminine and ultra-flamboyant side, and that my comfort level has allowed me to pass even better.
