This is no joke. The sex tourism industry in Thailand has made it a minefield for STDs; I remember reading in Laurie Garrett's The Coming Plague that at the height of the international epidemic, 85% of sex workers in Chiang Mai tested positive for HIV. That was a while ago, but Thailand is still no place for your husband to "act out" sexually and you should have him thoroughly fumigated upon his return so that he doesn't infect you with a case of antibiotic-resistant sea monkeys and blame it on your lack of dedication to your "therapy homework". I've seen hostess bars in Bangkok from the street and they are the tackiest, most meat-market misogynistic places you can imagine; the fact that a married man patronized such an establishment does not speak well of him.
