Need some good medical sites about human sexual health
 

Please, no trolling here.

I'd like to find some good informational stuff (popular science) about human sexual health and all around it.

Post them here

http://www.kinseyinstitute.org/ almost all you will need.

thx, that's a good one.

especially i'd like to get more scientific info on male and female sexual hygiene (like everyday's manual), penis and vagina health tips, sex improving tips, penis enlargement by physical exercises and scientific proved methods.

thx in advance

Must say good luck on the penis enlargement issue, unless operations are acceptable.
However you should check into the full reports they have. They cover just about everything sex.

This wiki may also provide some links and more data (hate wiki's). http://en.wikipedia.org/wiki/Masters_and_Johnson

btw it's almost impossible to find something worthy in google on this issue

let me know if there're any good books about this. i'll try to buy them.
