BTW: my older brother is depressed by his lack of success with women. I'd like to point him toward some helpful seduction resources but 1) I don't know how to do this without embarrassing him because, you know, it's dating advice from his younger sister and 2) I know a significant subset of that stuff is really kind of misogynist and nasty, and I'd rather not support that. Anyone have any brilliant ideas?

For point #2, I would suggest http://www.authenticmanprogram.com/ as an example of non-misogynist, non-nasty, non-just-about-sex "PUA" material.

For point #1, if he's specifically talked to you about it, maybe he's not likely to be that embarrassed?
