Looking for an alternative to tampons or pads? A user asks about menstrual cups, and we give her -- and you -- the scoop.

Throw a rock at any sex education site or service, ask what the most common question we get is from men and we'll all tell you that it's about penis size. We don't imagine with this piece we'll never get asked again, but we're hoping these answers get you guys better filled in so you can feel good about yourselves, your penises and whatever you do (or don't) do with them.

It’s typically assumed that sex and gender are the same. They’re not. What's gender all about, then? What is the range of gender and gender identity, and how does gender impact our lives and how we live them?

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.

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.

Puberty is the process of physical changes and sexual maturation leading to sexual maturation as well as complete body growth. During puberty, your whole body goes through growth spurts until it has become physically mature in terms of bone mass and size, and the sexual organs and secondary sexual characteristics develop and mature. Chances are, if you're at this website, you have likely already started puberty.

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.

If we look at our sexuality one way, it looks a million times simpler than it actually is. If we look at it another way, it appears a million times more complicated. While it's important that we bear everything in mind we need to in terms of infection and disease, birth control, our relationships, our bodies and the whole works, now and then we need to remember the bare bones and the human element of the thing, and keep the essentials in the forefront of our minds.

Tattoos and body piercings can be a great way to express your individuality, but they're permanent, after all, and not without health risks.
