I believe that most of us are on this forum because we perceive tgirls as being more sexual than than ggirls. Yes, it is a fantasy, but a very powerful one. Just look at the thousands of shemale and ladyboy sites on the internet. Many men and possibly lots of women seem to be very interested in the transsexual (shemale) image.
However, the reality of the transsexual, as Jodie has often pointed out, is a far cry from what is presented on the internet.
