What is it?
Sexual intercourse is penetrative sex. Any sort of sexual activity involving insertion: oral, anal or vaginal.
Here's how vaginal sex works.
The man needs to have an erect penis and the woman's vagina should have started releasing fluid to make it easier for the penis to enter.
The man pushes his penis into the woman's vagina (often with a helping hand to make sure it goes in right) and the couple move together however feels best for them.
The man or the woman may have an orgasm (come) during sex. Once the man has come, his penis will lose its erection and become limp again. The woman may need to have her clitoris rubbed (or to rub it herself) to have an orgasm.
The time before intercourse is foreplay, when a couple kiss and touch each other to get excited and lubricated enough for sex. Foreplay is an important and really pleasurable part of sex. Some women find it easier to have an orgasm during foreplay, especially if her partner rubs or licks her clitoris.
So that's the biology. But there's lots more to sex than just the mechanics.
How we feel about it. And after it. That's harder to describe.

If you're over 16, and you both feel ready - why not? But think about the consequences, they're big! I became pregnant at 18, and even though I felt ready, it's hard - The younger, the harder! I wouldn't swap my little girl for anything, but it's knowing you're ready. NEVER let anyone force you into it!
