I've been looking for a site to back up what I'm writing here, but I cannot find one. So, it's just my word.
A while back I saw a TV show about research into what type of face women found most attractive. This was real research done at a university. The researchers had women look at photos oh a model that had been altered with CGI. Some of the faces looked like amost like children, others looked more like women than men and lastly some were altered to look more like apes. They had the same women come in many times over a month and look at the photos and place them in the order from most attractive to least attractive. The findings showed that what a these women found most attractive changed depending on where she was in her monthly cycle.
Women that were ovulating for example found the man that looked more like an ape the most attractive. while THE SAME WOMAN at a different time during her cycle found men that looked more like women the most attractive. The difference was shocking even to the women themselves.
I'll keep looking for a web site with these findings to back up what I'm saying and post it if I can find it.
