Sorry I think this is bunk. I am a 67 year old man who is straight, been married for 28 years to the love of my life and am not blind. I can mane a number of trans people who I consider to be drop dead beautiful. I have two friends who are trans. Kind of hard to wrap my head around until I realized what this actually meant. If circumstances were different I would have no problem dating a trans-person, of course one could do better than I in the looks department.

Nonsense I know some trans woman that looks wise could put any genetic woman to shame.
Just like any woman each one is different looks size how they dress do their makeup.

If a person knows who is or is nto trans before making a value judgement of attractivenes, then the study would be flawed and biased.

It depends on the openness of other person tords a trans gender person. I think I would willing to date an trans gender person. Variety is the spice of life. I'm considering become a trans woman. What do we have loose by keeping an open mind.

Meh, just like anyone else, my estimation of a trans person's attractiveness would vary according to the individual.

That's sad. I can only speak for myself here and I don't feel that way. If anything, I think I believe the difficult social situation Transgender people face makes them more tolerant and understanding of differences. This would make them more attractive to me.
