Here's an interesting point I read from abcnews.com regarding personality profiles of gay men cruising for sex. According to Gershen Kaufman, a professor emeritus of psychology at Michigan State University and author of the book "Coming Out of Shame," :
"Public cruising is practiced mainly by deeply closeted men. Cruisers are not sex offenders. They are deeply, deeply closeted. There is a lot of self-hatred and shame and they can't allow themselves to come to terms with their sexuality. There is also the added element of danger and being discovered,"
