I've been out of the "hookup" game for nearly 10 years now, but I had my fair share of them prior to meeting my wife. Honestly, most of them weren't that bad, but there were a few that stand out like diamonds in a pile of slightly less shiny diamonds. There's no doubt that both spontaneous sex with a relatively unknown partner and "meaningful" "emotional" sex can be gratifying. There is a reason couples "role-play" to keep it fresh. That said, some of the acts and situations mentioned seem deplorable and I don't think I'd enjoy them much.
You mean acts like, "a young man masturbating into the mouth of a nearly comatose young woman, a young woman blowing a guy she just met because it "seemed like the thing to do," which is of course, next to a plug for a related story entitled, "Why Hookups Are Good for Women" ?
