It depends, as as traight man i think i would be interested on fucking a ladyboy only if she was close as possible to girl just without a pussy yea i think i would enjoy her despite having a cock. but if she had a masculine voice, facial hair, it would be a turn down.
Why dont you show us a picture of you and this way we could really tell you if a straight man would fuck you.
