The way I see it:

-increased disease risk
-getting a 'sleeze' reputation

I don't get that much pleasure from 'just kissing' either. I'd rather be more potent, and kiss less girls. Last night, out with friends, I only 'opened' one set (mixed 2m2f set) - really solid close (she asked for my number etc).

I'm also a bit anoyed that sapmi doesn't have too much success. Clearly from his message it sounds like something is going a bit wrong.
