SexDrive
Your sex drive (old word: libido) is your urges and desire to have sex. You should get a sex drive when you hit puberty. People have sex drives so that we reproduce and have children? and the human race does not die out. It's also ideal to get married and have a spouse. (This can take a lot of growing up and maturity before you can do it.)
Your sex drive may be the strongest drive you've ever had. You've been hungry before, I'm sure, but your sex drive is stronger. Your sex drive is on all the time, except when you're very sick or in a lot of pain, or if you've recently had sex. Have you ever felt in danger of your life, and had your survival instinct kick in? Your sex drive might be more powerful in the long term, because it never goes away.
I am told that boys and girls have equal sex drives, but I am also told that the male sex drive is 10 times as much, due to our testosterone?. A tenth of the typical male sex drive is still a lot.
It is generally believed that people cannot overcome their sex drives on will power, and will suffer a lot if they go without sex. People who are not having sex are more vulnerable to sexual temptation? (doing sexual things they don't want to or don't believe in), too. The cure for this is marriage. But, most young people cannot get married right away so there is the marriage gap.
