Never Think All Pretty Women Are Females

Yup, be extra careful. Bangkok has a lot of transgenders and drag queens (called ladyboys), and they are good looking. Some even more gorgeous than a real woman. You could easily mistake them for real women. If you are not sure, ask a local, but not the pimps or bouncers. Of course if that is your type of entertainment, enjoy what Bangkok has to offer. Some tourists go for this kind of entertainment. But, never forget that they have protection from syndicates.
