For me, I am sexually attracted towards crossdressers. I also have the same attraction towards tomboys. However, this isn't the limits to what I'm sexually attracted too. Its hard for me to give a list of examples of what I think is hot and what I don't think isn't. I would need to see an image of the person in order to say yay or nay.
Please note though that this isn't the only reason why I'm interested in crossdressing. While I do think it looks more sexually appealing, I don't have that as the only option. I've always liked femininity (but hid it away inside myself for the past decade), I've always thought girls clothing is more attractive looking than guys, and a lot of girls clothing is more comfortable to me. (Such as skirts for example).
I don't know how else I could really respond to this actually, so I'm responding to my best. Its always hard to explain how I sexually feel towards someone.
EDIT: A few things.
First off, I think this is my favorite thread in the site. :3 I like being open about my sexuality <3
Second off, http://www.timschraeder.com/2010/06/30/a-different-kind-of-demonstration-at-gay-pride/ I got this from serebii
Third off, Is there any words for transgendered people that you guys feel as insulting? A lot of terms feel to have negative feeling to them for me such as tranny, shemale, and even transvestite. Does anyone prefer the other terms, or do they not care?
