In addition to nerve endings, pleasure from anal intercourse may be aided by the close proximity between the anus and the prostate for males, and vagina, clitoral legs and anal area for females. This is because of indirect stimulation of the prostate and vagina or clitoral legs. For a male insertive partner, the tightness of the anus can be a source of pleasure via the tactile pressure on the penis. Pleasure from the anus can also be achieved through anal masturbation, fingering, facesitting, anilingus, and other penetrative and non-penetrative acts. Anal stretching or fisting is pleasurable for some, but it poses a more serious threat of damage due to the deliberate stretching of the anal and rectal tissues; its injuries include anal sphincter lacerations and rectal and sigmoid colon (rectosigmoid) perforation, which might result in death. Lubricant and condoms are widely regarded as a necessity while performing anal sex as well as a slow and cautious penetration.
“I hate to say I'm not a big G-spot believer. There certainly are some nerves, but [research hasn’t] been able to anatomically demonstrate much on a regular basis,” Mary Jane Minkin, M.D., a clinical professor of obstetrics, gynecology, and reproductive sciences at Yale Medical School, tells SELF. “I think women have areas that are more sensitive than others, individual exploration is good, and individuals can experience stimulation in all sorts of places."
In later Roman-era Greek poetry, anal sex became a common literary convention, represented as taking place with "eligible" youths: those who had attained the proper age but had not yet become adults. Seducing those not of proper age (for example, non-adolescent children) into the practice was considered very shameful for the adult, and having such relations with a male who was no longer adolescent was considered more shameful for the young male than for the one mounting him; Greek courtesans, or hetaerae, are said to have frequently practiced male-female anal intercourse as a means of preventing pregnancy.
It is often described as a feeling of fullness, which can be delightful. Most orgasms stem from the clitoris, including anal orgasms. The clitoris is the epicenter of pleasure for clitoris owning people. It is the only part of the female anatomy designed specifically for pleasure. For some vagina owners, anal sex can stimulate the internal clitoris, which is highly pleasurable.
So when you have vaginal sex, and the man cums then (most of the time) pulls out. What happens then? (not sure how graphic I can be here…) Some of the semen comes back out and gets on the sheets, your panties, down your leg… you get the picture. Ever noticed that if stay still on your back or it comes out pretty quickly, that it runs down you to the bed… passing near / over / maybe even slightly in the anus.
