I'm not saying that would be the main reason for me to go there, which is why I mentioned the culture etc. But we're only human and at the right time with the right person. Go even just for the massage. You might want to avoid the places where men just seem to go for sex. Chiang mai looks interesting. Cooler and not so garish as some places down south. Go for it Mac.
As for it being hollow. No more hollow than buying a a gift, drinks and dinner on a date for some woman you don't know in the hope of getting sex and company.

Vienna is lovely, make sure you try the sachertorte.
