Her boyfriend is 21, Whack-a-Mole, and has always been less hormonal than most guys. She’ll tell you that he’s still a demon in the sack, however. 
- About every 20 minutes. But I’m single, that may be why.
Oops, forgot one. Masturbate (usually) on a daily basis.
Some days I’ll just be bouncing along like normal and then my husband will kiss me on the back of the neck and I’ll be like freeeeeeow (as the immortal Zaphod would say).
I guess I’m like most people, I’m always ready for it. “Sex? Here, now? Why, sure!” 
And some days, and I don’t know why, I will practically glow with the supressed sexual energy, like a firefly blink blink blink. Those are the days…
But if I’m feeling grouchy or irritable, or if I have been working in the basement or something, I will absolutely want NO ONE touching me. Not even myself! I have to be clean and sweet smelling to even get in the mood, and I can’t be hungry or too tired.
Ugh, I’m 26 and masturbate never-you-mind 
Are you complaining because horny 19 year olds are posting? I, for one, find it very refreshing. Horny 19 year old girls post away!
Horny: quite often. While I’m not “always on” anymore, I am willing and enthusiastic about sex 95% of the time. The other 5% of the time I’m either sick or just Not In The Mood™. It used to be that I was always in the mood unless I was near-dead. I think that having a serious boyfriend, though, has made that wane somewhat–if I’m ticked at him, then I’m probably not going to want to have sex. Sometimes I just want to play around, though… <g>.
Masturbation: Daily. There are a few exceptions: bad period days, tired, know I’m getting some in the morning, but otherwise, I do so almost as though it was part of my schedule.
Female, married, 25. Libido of a rock. Once a week will do me, and even then it’s not horniness to the point of immobility (that happens about every other month). DH, OTOH, would be happy with twice a day, every day.
I wonder if I’ve already hit my peak and it’s all downhill from here. Not that I was getting laid when I was 18 but I sure did want to more than I do now.
I’m not picking on you Elysian, just an observation from a guy. All that is exactly why men don’t understand women. Grouchy, irritable, working in the basement, dirty, hungry, tired, NONE of those things would make most men not be horny! Well, maybe tired but… I guess it must just be a hormonal thing.
I don’t think it is necessarily a hormonal thing… I certainly wouldn’t want sex if I was hot, tired, dirty and hungry - so turn on the ac and let me get some food and a shower and I might be more willing…
Hubby was out mowing the lawn and in this heat/humidity he was hot, tired, dirty and thirsty. He wanted no more than a shower, a cold drink and a chance to relax. If I had asked him for sex at that point he would have laughed at me and told me to talk to him after his shower.
I think it is a matter of comfort more than hormones.
Age: 19
Horny: Like, almost constantly. Especially when I’m around my guy.
Masturbate: Every couple days
I’ve pretty much always been this horny. LOL. 
I am 27 and it has been more than a year since I’ve gotten any. I am horny most days although sometimes I manage to repress my hormones so that I can get on with life. Levels of horniness vary from “hmm I could use some skin on skin time” to “Can I please get fucked senseless? NOW!”
Masturbation tends to leave me feeling more frustrated than relaxed so I rarely bother although when the hormones are running at mach2 I might do something about it.
Age – 25.
‘sex’d be nice’ horny – pretty much all the time
‘wild monkey sex’ horny – about a week each month, sort of around my period.
Back when I was maybe 16 or so, I’d masturbate a lot (several times a day), but I don’t think I was any hornier. I just had less stuff to do and no one to boink. These days it’s every now and then, when I can’t have real sex for some reason (which doesn’t happen too often).
I’m 19, will be 20 in November.
I get horny several times a day. Yessiree.
I masturbate about once a day. Sometimes I will abstain for a few days to increase the intensity for the next time, especially before seeing a, er, good friend of mine.
Age: 28
Libido has skyrocketed since meeting someone who knows what the hell they are doing.
Ahhhhhh…so nice to have a man, not a boy.
Find myself having naughty thoughts about said man.
Masturbate rather often.
Eh, point taken. =P And it’s occuring to me that somehow when we 19-year-old women post about our horniness levels on here it comes out looking like the text of a spam email… =P Here’s something to think about though. There are a LOT of girls out there who are my age and older (and some twice my age and older) who have never experienced an orgasm and have never tried to get themselves off. I think that’s sad! 
I mean, how many adolescent males do you think there are out there who have never tried to choke the ol’ poultry? And I don’t think it’s always a lack of horniness so much as a general repression and lack of knowledge about it. With guys, it’s easy…it’s all hanging out right there in front of you. With girls, you have to explore a little more, and some find that extremely scary and don’t understand that it’s a beautiful, healthy, natural thing.
And yes…
yes, my sultry sister… you are so very right.
I am a firm beleiver in sex education not only from a health standpoint, but as an acquired life skill.
If I had known how to masturbate effectively as a teenager, I think I would have been a lot happier…at least more laid back.
I’ve had a high sex drive since my first “real” boyfriend (when I was 18) taught me what sex was “REALLY” supposed to feel like.
With a decently talented partner, I’ll want sex at least 3 times a week. Usually more.
I’m 44. And it, (the sex drive), is showing no signs of diminishing.
Same thing happens to me. If I’m not in a relationship, I gradually lose interest until I don’t think about it at all. I go dead from the neck down I guess.
Which is a blessing really. I mean it’s bad enough to be alone, but to be alone and have to deal with sexual frustration too??? ARgh.
Amen!
