During orgasm, the muscles in the genital area contract and pulse, I know it’s pelvic floor muscles.. What I don’t understand is WHY they do that during orgasm. I believe it’s a release of tension or what have you… But why do other muscles of the body not contract, pulse, and feel pleasurable to that extent when they experience relief of tension?
In: Biology
My understanding was that it was to pull semen deeper in, not a requirement but evolutionary pressure for conscientious mates.
This is one of the questions where the answer is ‘we don’t have an instruction manual or a requirements document, so we’ll never really know’.
My building orgasm (F) definitely triggers my partner’s and I’ve read that simultaneous orgasms are supposed to be advantageous for fertilization, which has always made sense with the way it seems to work with my body,
The Y chromosome leads to the production of the biochemical cues that lead to differentiation of development which embryologically are the same parts. Consequently, while there are differences such as spermatogenesis and ejaculation in men and Skene’s gland secretions in women, both sexes start out with the same anatomy. This, it’s likely more of an embryologic feature of generalized development of the reproductive system than some evolutionary advantage of pelvic floor muscles that contract versus those who don’t.
Other muscles don’t necessarily trigger various glands in your brain the way sexual organs do.
Imagine if you had an orgasm every time you sneezed. Could make for a difficult workday.
A common misconception is that semen ‘swims’ to the egg to fertilize it.
Sperm can move, but they do so quite poorly. Sperm is pretty much always transported to the egg by the pelvic muscles, which is why an orgasm feels good at does rhytmetical contractions to push semen to the egg.
1. Think about any body function.
2. Conceptualize how it might aid in evolution.
3. Chances are you got it right.
Ok, in this case, what helps from an evolutionary perspective?
Dick in vagina doesn’t cut it. You also need ejaculation, you need the sperm to get past the cervix, and maybe then you get some magic.
So, here are some things that dudes have that help this out:
1. Penis head is shaped like a reverse plunger. Why? everytime you go in and out, it creates negative pressure in the canal and cerrvix (nice.)
2. Dude gets hard and guess where you want to be when ejaculating? You guessed it. Balls deep.
So what do women have that helps this situation?
1. Pelvic floor muscles to squeeze the penis? Yep. Why? Cuz more sperm is better.
2. Tight spaces make harder ejaculation? Yep, so sperm get further up the canal and nearer the cervix on and immediately after ejaculation.
Ok, you see whats happening here? Everything that ‘feels good’ is part of the system that sets the precondition, then during and immediately after orgasm helping the delivery get as close as possible to the place it needs to be.
Bodies are cool things, but they are way cooler if you think about them from an evolutionary perspective.
It’s been suggested that female orgasm increases the likelihood that sperm are introduced to the cervix and therefore have a higher chance of fertilizing an egg. While not 100% true (so don’t come after me, comments), women tend to have orgasm with male partners they are compatible with, attracted to, and men who are invested in their pleasure. The dark contrast would be women are significantly less likely to orgasm with men they aren’t very interested in, or even worse men who rape them.
Remember that evolutionarily having sex is a major investment for a woman and their biology is engineered to look for higher value partners who are likely to support and protect them during pregnancy and while raising a child. So if orgasm is indicative of heightened interest in their partner and attention from their partner, it pairs well with their evolution to increase the likelihood of fertilization during those encounters versus low-value or forced sex.
I always wondered why you get the ol’ butthole clench during orgasm. Because yes I have farted during an orgasm before due to that
Bc the Contractions help the little swimmers make it to the imposed destination.
