Sex definition:
Regular version-Intercourse between a man and a woman, or two of each if that's how one swings. Can be done in many places, including the ear(NOTE: This is from Family Guy. I do not know if you can truly fuck one in the ear).
Religious version-Same definition as above, except when you do, you must have a child. And the 'two of each' is excluded.
I learned of sex young, because in Dominican Republic, it seems they aren't as afraid of kids learning about it than in the U.S. They literally had children picture books, which I would read to look at the happy pictures of a man on a woman. So at about, let's say, 6 or 7, I knew the basic of sex: It creates children. [small] Durr. [/small]
By 10, due to my older siblings that have corrupted me, I knew about things such as Hand Banana, rape, condoms, and other fun things. And by 12, I learned all about the different kinds of sex: scissoring, oral, anal, 69, 68, and the others. I even found that some positions are good for pregnant women.
And then I learned you can have sex while pregnant.
My belief on having sex is that you should have it when you feel mature enough. This may be 16 or maybe 25, but I say the point at which one can make a decision is late 17. 18 is when everyone says "You're old enough," but if one does not feel ready, then don't go pick up the next random girl and ask, "May I place my penis in you?" And if you go by your religion and think you must do it a certain way, then okay. Just don't force your belief upon me.
So basically, I think you should wait until you're about 17-18. Then you can decide if you feel ready, or if you want to wait.
...MAKE A DECISION! D:<
