Heterosexual intercourse occurs whenever a man puts his penis into a woman’s vagina. That’s the minimal definition. But sex is about more than that simple act. As such, you may be curious, or you may want to know how to describe sex to a teenager. The information below explains what — exactly — happens during intercourse.

What is sex, exactly? In other words, what "counts" as having sex? And when do you stop being a virgin? Sexual relations cover activities beyond intercourse: They also include outercourse, oral sex, and anal sex. So what are the differences and how do they impact virginity? One thing that all forms of sex (outercourse, oral sex, anal sex, and intercourse) have in common is that they involve two people giving each other the pleasure that comes from having an orgasm.

Masturbation is, in fact, a basic part of good sexual functioning. The myths about going blind are most definitely untrue, and masturbation is a healthy part of growing up. If, however, you are just exploring sexuality, you may be wondering exactly how to masturbate (or how the “other half” masturbates). Keep in mind that, while you can read about the most common ways, there are many ways to enjoy sexual pleasure on your own and no “wrong way” to masturbate.

What's the right age to start having sex? When to start having intercourse (or any other type of sex) is a very difficult and serious decision to make. Some people believe you must wait until you're married before having sex. Other people may not have a problem with premarital sex. You're the only one who can decide for yourself — although there are important factors to consider in that decision.

Understanding women's sexual (or reproductive) organs such as the vagina, uterus, and vulva is as integral to sex as understanding the penis. Demystifying female anatomy is key to good sexual functioning, whether you're a mature, experienced adult or looking to learn about women's sexual organs for the first time.

One of the most common problems that affects sexual functioning is a heart attack. If you or your partner has recently suffered a heart attack, you may be wondering when you can have sex again. Or perhaps time has passed and you’re starting to wonder if you’ll ever have sex again. The good news is, even after a heart attack, a healthy sex life is possible.

Is masturbation normal at a young age? Most parents don’t expect to find their toddler son with an erection, or their kindergartner girl rubbing her genitals. So when does a kid normally start to masturbate? And when is masturbation safe? Masturbation in childhood Rest assured that masturbation is a healthy part of growing up.

One of the biggest questions for teens isn’t “Should I have sex?” but “How far should I go?” While one’s own comfort level and that of the partner should be the top priority in this decision, other factors play a role — especially if teenagers are considering that amorphous concept of “third base.” “Third base” probably sounds outdated to today’s teenagers.
