No, this is not an incentive to fuck (that could happen later after viewing).
A co-worker of mine handed me a list he found on the Internet. I don't know how reliable the source is, and issues of what turns people on tend to be vague. In fact, it seems like every hour there's a list that pops up somewhere, ten body parts women find attractive in men, or what a gay guy finds hot on another guy, etcetera, etcetera.
