How much does having a kid kill their sex drive?
It depends on their age and depends on the woman.
A significant portion of pregnant women become much hornier! When that happens, they often get used to being hotter, hornier, and dirtier - seeking out their man (or more men, as the case may be).
For these women, getting preggers AGAIN (and again) may well be desirable for them, Or else there are other outlets, male or female or even porn. Being a horny mommy can become a lifestyle for many.
About one-third of women do not find their sex-drive affected by aging out of youthful beauty. But a majority do within the 26 to 34 age range. This is when female testosterone maxes out and women think most like a man, needing more and loving more sex! (And don't start me up on estradiol/testosterone ratio issues, whatever! Anti-male and lesbian American feminists saw to it that "Human Sexuality" textbooks in the 70s that mentioned this issue no longer did by the 80s. I know because I've looked.)
I am active on a Hotwife site (women who enjoy threesomes, usually but not at all always with males, or else someone on the side). We ran a member survey of the women on the age they decided they enjoyed more than just one man's dick in their life and needed variety. (Mind you, ADD/HD and Bi-polar women and men both are prone to this way of copeing with their disorders.)
We discovered that 31 was the median age - half older, half younger. This corresponds well to the age of maximum female testosterone. And a full one-quarter do so by the time their college years are up.
In my experience, the more sexually adventurous people are, the more they are simply accepting, enjoying, and using their higher sex drives.
There may be one useful external marker for a woman (or man) being higher than averagely sexed: a double chin!
(Mind you, I'm trying to get psych grad student friends to do this research properly - with Facebook and other online data bases out there, the raw data is available. Further more, there are also studies showing another genetic/his sex-drive link: namely, that men with feminine facial features and women with masculine facial features are higher sexed. So my theory is not with out precedent.)
THINK ABOUT THIS correlation in your leisure time: how often are Hollywood movie stars/porn stars also with a butt-chin?
Among the first, over 80%. Among the later, 90 to 95%. (The obvious variable needing to be controlled for this study is exhibitionistic traits.)
That may help a man in choosing a woman with high-sex potential.
Another thing a man can do is much more important: teach her to enjoy FREQUENT and wild orgasms or become a better lover - hopefully both! The first can be accomplished by buying your woman a vibrator (at least two - pocket rocket and Hitachi Magic Wand, or similar). Teach her to masturbate - and do so with you as part of foreplay.
The second is greatly helped by by knowing how to give your woman G-spot orgasms. There is
an epic ten year-long thread at Literotica.com, "Try This & Report back" (with 135 pages) by "Mr. G." on doing so! (
HEY, has no one written a book about this thread yet???? Oh well - I've got too many book ideas anyway.)
Orgasmic freaky women are the most fun you can have in bed! Teach her to love orgasms and I don't think children are much of a barrier to enjoying sex more and more. Most women who love it young will love sex more as they grow older. In part, pregnancy makes a woman more curious about their body's potential for experiencing pleasure.
(YEAH - I know, this might need another DATA SHEET somewhere here.... But later.)
To sum up my answer question: other than in being exhausted by childcare, having children need not diminish a young woman's sex drive. Choosing or teaching a young woman to enjoy being more sexual is the best way to avoid this.
Now, how much being religious or too traditional with "my parents didn't have sex" attitudes could change this happier outcome is a different matter. And I-exactly don't know!
