Well here's Uncle Kenny's definitions:-
Ladyboy/Katoey- guy's with BOOBS:looks like a girl untill you pull down thier pants.
Princess Boy - (my own category) Boys that have been taking hormones and have small hormone breasts.
Usually pre-ladyboy. Will usually wear training bra or other top in a go-go bar
Fem-boys - effeminate gay boys and definitely bottom.
Bars for ladyboys: in Pattaya- Jenny Star Bar(walking street), Stringfellows, Club 131 (soi Yamato)
In Bangkok: NanaPlaza- Temptations, Cascades and Cassanova
For Princess boys/fem boys- Blue Ice on Walking street - also many go-go bars if you look carefully you will be able to pick them out.
There is a raging debate about if Ladyboy-lovers are Straight or Gay or confused.
The Straight guys think its Gay and the Gay guys think it's straight.
I suggest you don't worry about it and just enjoy yourself.
