I just wrote about the problems with abstinence-only education not very long ago. I know my teacher reqested that i not use ONLY websites or liberal sources, so i'd suggest try and avoid all the planned parenthood sources for all your work. I found a lot of info off a magazine/newspaper database my college offers, which was SO helpful. Sadly it's limited to only students so i can't give you any links but if you have one in your college/school try and use those. There's TONS of info on the flaws of JUST teaching abstinence-only education, however most studies claim that teaching it along with sex education is the most effective.
