There was selective pressure to obscure the fertile period. The main biological and scientific purpose of sex is reproduction even if people have sex for other reasons If you are really afraid of getting pregnant, you can choose to not have sex, or you can take the risk and try to minimise the risk, but if you do get pregnant you shouldn't kill the baby you conceived. For the people arguing that sex isn’t solely used for procreation, and is used for bonding or creating/expressing intimacy between people, this is almost expressly for reproduction. “purpose” is, as others say, not a great question from a biological perspective What we can say is that species that reproduce continue existing, and species that don’t reproduce do not continue existing, so over time, species that reproduce will stick around while those that don’t will not.
Never heard this before some view sex as sinful unless married, or as the purpose should only be reproduction Reproduction is a beautiful thing indeed but you're not evil if you don't reproduce Intimacy and connection are also a beautiful thing Not everyone is going or wants to have kids , and if that's their preference that's ok. Only purpose of all life is reproduction and it goes on and on forever.only purpose of this generation is to create another, and of that one to create one more There is no purpose or meaning outside that cycle.people believe in god or magic or anything but in the end most will do what they are made to do and then die.then their children will believe in some stuff or not and they will still do.
This is called natural family planning (nfp) Nfp is not contrary to nature because it in no way frustrates nature’s design for sex It is nature’s doing that the woman doesn’t conceive during.
