Several forms of contraception have been used since antiquity -- herbs, barriers, condoms, spermicidal lotions, sponges etc.
Otherwise how do you think whores would avoid pregnancy? They did use contraception.
What changed in the 1960's is that contraceptives started being pumped and promoted into the mainstream as if it were candy.
Worse: the estrogen pill not only prevents conception but it also modifies a foid's hormones, driving her to adopt destructive habits in her behavior -- such as wasting two decades of her prime riding the cock carousel in a quest for the strongest emotions she can get -- when in fact the strongest thrill a foid can get is to simply be a submissive housewife to a decent guy.
A foid not on the pill is much more inclined to settle down with a decent enough male, and start having babies earlier, while a foid "on the pill" is much more likely to wait until she's 35 and has become infertile after having collected semen from 1000 donors before she realizes she's wasted her life, fertility, youth, etc. by studying, working, consoomin, riding the carousel and repeat.
The pill is not only contraception, but it is a behavior-altering drug, a lifestyle drug.
