A candid memoir of first-time intercourse from the founder of Scarleteen.

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.

I'm writing this because someone told you that you can't understand or experience love at your age. If no one did yet, they probably will soon enough. I'm writing to tell you that if you've heard that, I just don't think it's true.

This is not another article about how everyone you meet on the net is an axe murderer. The Internet can be a great way to communicate - that’s why this website is here, after all. Many people successfully find friends, girlfriends or boyfriends over the ‘net , and some of my closest friends are people I first met online.

Rape is often framed as about women, but it's not. Something done TO us really isn't about us. It's the things that we choose to do which are about us, which is why it's such an error for rape to be framed as a women's issue or about women: it's almost always a men's issue and really about men. Find out what men need to know about rape and rapists, what you can do to be sure you have consent with sex, other ways to help with rape prevention, and why your help is so important.

When breakups do happen, as they almost inevitably will, they are rarely painless. Guys in particular are often surprised by how badly the end of a relationship can hurt, and are particularly vulnerable to feeling isolated, lonely, and without anyone to turn to to process through that pain.

The biggest part of the battle with relationship problems isn’t fixing them so much as it is recognizing that there ARE problems, what they are and being willing to address them and work a little to seek out healthier patterns of behavior.

You can read everything from the Kama Sutra to The Joy of Sex, watch porn vids until your eyeballs fall out, have a ton of sexual experience or psychically channel Mata Hari or Casanova, but if you don’t know how to openly communicate with your partners -- with your words -- chances are neither you nor your partner are going to have really healthy, beneficial and satisfying sexual experiences, especially in the long-term. So, read up and start talking!

I’m going to suggest you look at reciprocity in sex -- the idea that one person gives something, so the other should get something of equal value back -- in a different way than you might be used to. (Excerpted and adapted from S.E.X., the Scarleteen book.)

Talking with your parents about sex can be really hard – even if your parents are really open and start the conversation themselves rather than you starting it – or even if your parents are totally supportive of your boyfriend or girlfriend and your sexual activities. Here are some tips and helps to make it easier on both of you.

That older boyfriend of yours, the one who keeps pressuring you for sex, who's got you scared you're pregnant for the 38th time, the one who is supposed to be the grownup, but acts like the child? The one who seems to keep mucking up more and of your life with every minute that passes? Yeah, THAT guy: I have to admit that I am becoming seriously pissed off at that guy, for a whole lot of reasons I want to tell you all about.

We talk a lot about sexual safety and safer sex here at Scarleteen in terms of your physical health. But what about checking in to see if sex is safe for you and yours emotionally? Taking care of your emotions, looking out for risk factors in advance -- not just when they become an existing crisis -- and safeguarding yourself, your partners and those around you from needless hurt and harm is just as important as doing what you can to prevent STIs and unwanted pregnancies.

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.

Is your boyfriend or girlfriend more than a couple of years older than you? Here’s a scoop on age differences and what to watch out for.

Many people in long-term, committed relationships, be it marriage or steady partnership -- no matter their age -- have ideas about sex in partnerships they may not even be aware of. Often we base our ideas of relationships and sexuality on what we see in the media or in movies, on what our parents relationship is like, or on what we imagine, in a perfect world, sex and love to be. Talking about what those ideas are, communicating our feelings honestly, and creating clear limits and honoring them make everyone happier and healthier.

Relationships can be confusing enough as it is, but if you and your partner don't live in the same area, it can get doubly complicated.

Do you ever watch those reality TV shows where someone gets a total life or personality makeover, and wonder when a TV crew will come along to “pimp” your life?

You can take the steps to change and improve your life for the better, all by yourself, and without that pesky camera crew there to catch your most embarrassing and trying moments.

Never believe: "I love you, it will never happen again." It will happen again. The tears don't matter, the bruises don't matter, the broken bones and ER visits and warnings from friends and relatives don't matter. Those scars that we bury deep inside us, the mental and emotional scars that we try to pretend don't exist -- they don't matter. It will happen, again and again and again, unless someone puts a stop to it.
