If your
period has ever been late, you know how scary and stressful it can be if you're not trying to get pregnant. Knowing some basic facts about sperm and the male body can help prevent an unexpected pregnancy, or help you avoid the anxiety of worrying that you are pregnant. So take this short quiz to make sure you're up on your sperm smarts.

Many women are on the pill because they love how it regulates their periods, reduces symptoms of PMS, and prevents them from becoming pregnant. What they don't love is having to remember to take their pill every single day — that's where the

What you do in the bedroom is totally your business, but I thought it was high time we talked about something that's a little taboo — anal sex. There, I said it! I know some of you may be a little shocked that I'm talking about this, but just like with all things having to do with sex, it's good to know the facts.
