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
First of all, the main reason for the contractions is to facilitate ejaculation.
Second, there is enough similarity between male and female genitalia that these contractions are also present in females, even though they don’t need to ejaculate. I guess you could say evolution didn’t bother to prevent females from experiencing muscular contractions during orgasm as well because there was no motivation to eliminate it.
They are similar because if you learn about how genitalia is formed in a fetus, they start off the same but diverge to form the male or female genitalia that we are familiar with. If you want to read more about how genitalia is formed, look up Genital Tubercle.
