I hope this does not offend anyone
but why go with a TS?
is it forbidden fruit?
is it a BI thing
i don't understand or see the attraction?
Again not trying to offend , trying to understand
I think any guy who says he's not interested in cock should think long and hard (pun intended) next time he wanks himself. Most guys love their own cock so it's just a question of whether you're attracted to what's attached to the cock.
I've always considered myself bicurious, but I'm simply not at all attracted to men or masculine features. I remember accidentally winding up on one of the TS alley's in Amsterdam in my youth, walked up and started a conversation with a (I thought) very sexy if amaz0nian blonde lady, only to notice her adam's apple and a few other clues - and then I just couldn't get past it.
For a long time I thought I just couldn't be attracted enough to a TS as they would always look masculine, but then I found a couple of actresses and trans activitists who I was very attracted to (Nicole Maines for example).
I also do enjoy some TS porn assuming they are extremely feminine. So I've had a bucket list item to fuck a TS for a long time.
So every TS review here I look at very carefully and check out their pics to see how feminine they really look. I now do have two or three that I think might fit the bill...just building up the balls to do it!

Julia Castro is top of my list but I understand she's next to impossible to get hold of.
Luna Rodriguez and Bela Marina are up there as well.
So yes, for me it's definitely a bi thing, but also I do enjoy exploring taboos.
