Ok, here are some thought from my surfers experience:
less nudity makes me more horny. An idea: " OMG, will this girl realy take her clothes off " comes to my mind and I feel an urge to see her nude.
So showing a girl with clothes in the first thumbs or in the first big thumb seems to be a good tip.
A girl with a smile seems to make me horny too. She seems to be more outgoing and I think many people like it.
What do you think about it? Please add your thought.
