Not really lol. The act of riding/taking TS dick kind of puts you in the role of a female in terms of sex, so I don't think anyone who wants to be fucked by a lovely t-girl cares about how masculine they look in the process. I certainly don't. I love dick lol.

I will say some male models who bottom annoy me because they're too loud. I don't personally wish to hear a hairy man scream and moan constantly. I like the domination factor, and that's a big reason I dig girls who top and I like the focus to be on her in porn. But in real life? Nah, don't care lol. If you're worried about how macho you look with 10 inches of girl pipe in your bum, I don't think this fetish is for you :P
