Men are pretty much genetically programmed to seek younger, prettier women. I'm often perplexed as to why men are blamed by women for seeking what they are essentially programmed to seek. We want them because WE find them attractive. Why should we be bound by what YOU think we should find attractive?
Now, I'm sure the 30-something sisters you are referring to are probably fine women, and perhaps quite attractive. But if a guy has a chance to date a girl who is younger and even prettier, well, he will likely do just that. It should not be news that men like women who are "younger, thinner" and "prettier". Men should not be condemned for wanting to follow through on what they naturally desire.
