Both males and females KNOW that a males sperm and a females ova, when coming together, create a child.
Birth control pills. Condoms. IUDs. Spermicidal jelly. Hysterectomies.
ALL of the above have been defeated by LIFE.
(Yes, even women who have had hysterectomies have had children who have attached themselves to other parts of females bodies and grown to the stage of birth.)
The only way to ABSOLUTELY GUARENTEE no pregnancy is…ABSTINENCE.
OH! HORROR OF HORRORS! NO…SEX …!!!
No…let us ALL have SEX. And as much as possible.
But only in the context of a male and female who look forward to a child - and are commited to both each other and any child who would be born of their love and committment.
OH. MY. GOD. !!
That sounds like RELIGIOUS FUNDUMENTALISM!!
We must run from it.
Run from it.
Just, PLEASE, be ready to commit to any child you may create for the next twenty-one years before you f**k.
It just may happen.
And the rest of the world must take up the slack for the contingencies you fail to provide for.
