A man named Jason Evert came to our school and gaved us a detailed talk about his point-of-view of sexuality. He's a devout Catholic...
...but don't let that stop you from reading his work, because he backs up his ideas with lots and lots of extensive and evidencial secular research.
Here is the site on which he provides information about chastity, pure love, and his (well-researched) viewpoints on pornography, masturbation, and contraceptives (as well as several other interesting topics involving sex):

Enjoy, world! I hope you are more accepting of my (er... Jason Evert's) word than the people of HeavenGames forum have been!
God bless all of you, and Happy Saint Valentine's Day!
