Jimmyredcab, you are right, sir. I can't explain it - maybe it's one of those things where you try stuff just to see what it's like, and you can't explain why you like it, because all rational thinking tells you that you shouldn't. As you'll see from my post on the other thread, the first encounter I had was pretty weird precisely because the girl/guy looked rather masculine, even with all the make-up. The second TS escort I saw - TS Valentine at Yummy Asian - looked completely feminine even close-up - you really couldn't tell.
Now OK, I know what you're thinking: "even when they look 100% feminine, what about the slight giveaway between the legs!!?!?!? And that's the point at which I admit that I can't explain it. Would I fancy a hairy-arsed lorry driver? Or for that matter, a male model? Not in a million years. So does that make me bisexual? I don't think so.... BUT, I have to admit that with TS Valentine, I got turned on receiving AND GIVING oral. So surely that means I'm bi after all? Maybe a little bit bi? Who knows? And does it matter?
I suppose there are some things that it's best not to think about too much, and instead just go with the flow. And for me, seeing a TS escort once every year or two falls into that category. I know there are those on this site who can't understand that, and I totally accept that (that's the great thing about this site, in my opinion). For me, a rough equivalent would be watersports. Never pissed on anyone, never been pissed on, and the whole thing makes me feel pretty sick to be honest. But others like it.... and who am I to judge?
