I have an extremely high sex drive

You were like this when you were ten years old? HA!

Yes youre a normal male thinking about sex every 7 seconds. Just jerk off a lot or get a girlfriend and use birth control.
If all else fails get a blow-up dummy.

Your young and you have a lot of testosterone you are like at your peak right now I have a high sex drive too and I am 46 I still masterbait at least once a day but I have read that as you get older your t count testosterone goes down and that's when you need things like Viagra

young and dumb and full of cum.. i've been there

I was like this forever.

Im a female, 16, and you Basically just described me
Lol
My ex and i broke up because he felt that i was "using him for sex" but that wasn't the case at all
We went on dates and stuff and said ily, it wasn't JUST sex
But i guess i wanted so much or just being physical in general, it was too much for him to handle
Ive learned to quell my "desires" when i need to now tho just incase i meet another guy not as into intimacy as i am :p

So my answer is
Yes, not because Alot of people are constantly thinking "sex" lol, but because you aren't the only one :)

"Extremely High Sex Drive".. Compared to what? To whom? Surely if you know it's 'extremely high' compared to other people your age, you know it's not that normal?

It's normal to have a very active sex drive when you're a teenager. It's NOT normal being in a state of arousal 24/7. It probably doesn't matter either way.
