There are 3 listings for a TS Pataya. I hope your review is approved, so we can read the details. So, without know for certain......
Differences abound among us and so it is when topped. To me, being topped represents a significant step beyond our social boundaries.
If you're like me, I've never played around with guys, and really don't care to. So, when I saw my first TS, it was really new territory, so to speak. Even so, the fundamental aspects of sex with a female were all there: touching, oral, climax, etc.
However, being topped introduces a completely new dimension of experience and may even conflict with the femme persona, at least as some might perceive it.
Furthermore, if you're like me, I don't keep a dildo in my ass all of the time, so I imagine things can get pretty tight. So, there may be some discomfort during sex: she's too big, condoms can sting, run out of lube, etc.
Finally, I suspect that the newness of adding this activity can be distracting. In some ways, I suspect it's similar to genetic girls having intercourse for the first time. There's a degree of uncertainty that can actually interfere with the mood, and I think mood is essential for being topped.
In other words, it's likely that the more you are topped the more you will enjoy it--assuming that it's something you really want to do. It will become one of your normal activities--normal but not routine, standard but not boring. You'll learn to unleash the inhibitions, groove to the mood, and collapse the walls of doubt.
And, this is important, bottoms learn to stop micro-managing their sensations, learn to let go of any paranoia and yield to the top.
Doing it more often will likely lead to better sex--mentally and physically.
Hope this helps and glad for your post!
