Want to know what to expect at your first gynecologists' or reproductive health exam? We've got the lowdown for you here.

A basic lowdown on interpersonal abuse and assault: what all the terms mean, why strangers are the least of our worries, what a cycle of abuse looks like, how you can start seeing abuse for what it is, where it is, and how to protect yourself and others and make abuse stop.

What's a "boyfriend" or what's a "girlfriend?" It all depends on what you and yours decide it's going to mean and what works best for you.

If we're going to think of our genitals as big, any one of us, given the small range between them, we should think everyone's genitals are big. We also need to accept that it's ignorant or misinformed to think, presume or suggest that penises are big but vaginas are small, because we really are all about the same size. If thinking big is better for one sex, it's also got to be better for the other. So, if you or someone else is going to go on about some big penis, you'd best get just as excited about the idea of a big vagina, and make having a big ol'Vagowski just as cool. And if you're all hung up on the idea that the vagina be as small as it can possibly be, or is such a small thing, then you've got to accept that penises are small, too.

Let’s just say – just because we can – that we, all women, in every sexual scenario imaginable, are already past both the no and the yes. Let’s say that nothing even starts without that yes, and that when it is issued, it is firmer, stronger and more exuberant than we may be able to presently imagine it could be. Let’s write a new ideal sexual initiation script. One that's a lot more interesting.

We get a lot of questions at Scarleteen from folks who are worried about periods that are MIA (missing in action, for us civilians). Sometimes there's a pregnancy concern, and sometimes not; but even if you're not sexually active, a missing period can be worrying.

The next time anyone tells you that only losers masturbate, or that they don't, and never would, bear this in mind: according to most studies and surveys, about 95% of adults have masturbated or continue to do so. Were many falsehoods and misconceptions about masturbation true, it would mean that 95 out of every 100 people would be blind, drooling psychopaths with hair on their palms and shrunken genitals.

Vaginal discharge and secretions are a normal, healthy part of your reproductive system. The vagina -- which is not the whole of your genitals, that's called the vulva, but the flexible tube behind the vaginal opening and inside the body -- is a passageway between the outside of the body and the internal reproductive system. The pH balance of the vagina is acidic, with "good" bacteria, by design, which helps keep infections away. Vaginal secretions are how the vagina cleanses and regulates itself -- how amazing is that? -- in the same sort of way that saliva helps keep your mouth clean and healthy.

This is not another diet guide. It will not show you how to lose ten pounds by Thanksgiving. It will not introduce you to a new set of "miracle ab crunches" or rave about the latest liposuction advances. And there will be no butt pads, silicone, or fat-free recipes to share.

A big part of keeping yourself sexually healthy is maintaining your sexual and reproductive health in the first place, and paying attention to your sexual health daily so that you can get the jump on any problems that may crop up.
