These questions are totally out of "ignorance" on my part so absolutely not intended to offend anyone.

I have seen several "TS" reviews, along with their pictures and they get me very excited with the beauty they present themselves with.  To me they clearly look like females in most cases.  Now to my question(s):

Is a "TS" a female that is planning to become a male -or- the opposite?  If it is both possibly, how can a person politely check this out prior to engaging in a session with them?

My interest would only be if the "TS" was a female a birth....

Any suggestions for Vegas encounters would be greatly appreciated...
