I’m a lucky man to have such a woman as my lover. But the story is really to say that anal sex is horses for courses. She at NO time ever complained of pain or discomfort on her first trip down Sphincter Alley. I know I would have!! We went the full Monty next time and I got my cock really deep into her and man, she was just going wild! It was just slowness and patience and above all utter relaxation that gave her such an easy and joyous initiation. Take note.
In a 2010 clinical review article of heterosexual anal sex, anal intercourse is used to specifically denote penile-anal penetration, and anal sex is used to denote any form of anal sexual activity. The review suggests that anal sex is exotic among the sexual practices of some heterosexuals and that "for a certain number of heterosexuals, anal intercourse is pleasurable, exciting, and perhaps considered more intimate than vaginal sex".
The anal sphincters are usually tighter than the pelvic muscles of the vagina, which can enhance the sexual pleasure for the inserting male during male-to-female anal intercourse because of the pressure applied to the penis. Men may also enjoy the penetrative role during anal sex because of its association with dominance, because it is made more alluring by a female partner or society in general insisting that it is forbidden, or because it presents an additional option for penetration.
The anus is surrounded in its length by folds called anal valves, which converge at a line known as the pectinate line. This represents the point of transition between the hindgut and the ectoderm in the embryo. Below this point, the mucosa of the internal anus becomes skin. :397 The pectinate line is also the division between the internal and external anus.

Using a new condom is especially important if you’re switching from anal to vaginal penetration so you can avoid moving bacteria from your anus to your vagina or urethra. Your anus is home to all kinds of bacteria your vagina and related parts aren’t used to—namely, gastrointestinal (GI) bacteria, like E. coli. When this bacteria reaches your vagina, it can cause vaginal infections, like bacterial vaginosis, which can lead to vaginal itching, burning during urination, a “fishy” vaginal odor, and gray, white, or green vaginal discharge, according to the Mayo Clinic. It can also spread to your urethra, where it can cause a urinary tract infection. According to the Mayo Clinic, this can cause symptoms like constantly needing to pee, then a burning sensation when you do, along with cloudy urine and pelvic pain.
The tissue and skin around the anus acts as a protective barrier for the bottom half of your digestive tract. However, the tissue inside the anus is thinner, delicate, and more likely to tear and bleed as a result of penetration. This increases the likelihood of passing infections, viruses, or bacteria between partners. Even two partners who don’t have any sexually transmitted infections (STIs) can still pass bacteria between each other through these tears in the skin.
