I see sex sort of in the same way I see food. Just like the biological purpose of sex is procreation, the biological purpose of food is to nourish and sustain our bodies and health so we can live long enough to reproduce and raise children to be adults to perpetuate the human species. We could eat the same bland foods every day and get all the nourishment we need, but most people (including me) prefer to eat a variety of foods that are flavorful and pleasurable to eat. We also like foods that are visually appealing, which is why nice restaurants always take steps to make dishes look appealing on their plates. Food can be bland and boring, or it can be exciting and pleasurable to eat, and we're more likely to eat it if it's not bland and boring.

The same is true for sex. Not that vaginal intercourse is bland and boring, but there are lots of other things that can make a sexual experience more exciting and pleasurable. Orgasms are definitely one of them, and oral sex gives me more of those than anything else. And anal sex can make my orgasms stronger and more intense.

If sex becomes bland and boring, people will stop doing it. And if that happens there will be no more babies and the human race would go extinct. So I guess the biological purpose for things like oral and anal sex is to keep sex exciting so people will keep having sex and keep reproducing.

oral sex has it's purpose for sure... almost always when i give a blowjob and he cums in my mouth i feel satisfied and happy... guys don't know it but i give a blowjob because i like to give them and they excite me to no end... but they will go on thinking i'm doing it for them which isn't true... they think i need pussy eaten truth is i just need my mouth and lips wrapped around a cock... all this talk about naturality but 99% of men will run when they get you pregnant but they speak of how much they like cumming in your pussy... thank god for oral sex

Dominance, you aren't making babies but marking someone else as yours, which they are being marked as taken. Birth control is a very new invention, and keeping a woman pregnant consistently when she hasn't recovered from having a kid can be deadly. It isn't advantageous to have a child, get pregnant, then die of malnutrition or during child birth, possibly leading to the death of your previous child, current child, and yourself. Or as a man to your spouse, child, and infant.

Otherwise men would only enjoy the feeling of vagina and wouldn't enjoy masturbation, blowjobs, so on and so forth if we were meant to only impregnate. We've had many generations for that to drift in different directions if it wasn't advantageous. On an interesting side note, maternal mortality has started rising in the US as the age of mothers has been increasing.

There is no biological purpose other than people have conditioned themselves or have been conditioned through viewing pornography, peer pressure, or pop culture trends to preferring such methods and unnatural ways. Some of these ways such as anal are actually harmful and carry a number of risks. Other ways are just degrading primarily to the women such as when men require a woman to swallow. Now if a woman enjoys it then fine. But again there is no real biological purpose other than an alternative way for stimulation or adventure.

Vaginal on the other hand is the ultimate for me. I was raised in an environment of appreciating the natural side to the human body. I was taught at a young age the anatomically correct way in which a male and female should interface sexually. I have always been more than content with PIV.

Don’t think there’s a biological component to either one, but so what? The purposes are super clear though — pure pleasure.

SaoirseS · Answer

There really isn't any biological purpose. There isn't any biological purpose behind kissing either.

I think there is no purpose whatsoever for anal intercourse. But the purpose of oral sex could be to cause additional arousal on the part of the female and make her more both accessible and fertile for impregnation.

Anal is to give the man a prostate orgasm, his G-SPOT, basically. Oral, is just to help get them going, ya know, turn them on, so that it makes it easier to have penetration
