Depends on what is meant by anal activity. Many women appreciate a bit of anal touching or licking....think of it as knocking on the back door. Most will not open the door because of the embarrassing….umm….clutter behind the back door so it's rarer to find women who like anal penetration. I think it's very rare for a woman to exclusively use the back door when the front door is so accessible and clutter-free. As for me, it doesn't matter where my partner puts his cock as long as I get off….I enjoy it inside or rubbing outside, front or back, although variety helps me cum more.
But why would a man stop seeing a woman because she is into anal activity? I think most men would like anal sex if they can embrace the naughtiness. I've had partners express concern about hygiene to which I assured them my back passage had been cleaned, or I initiated them with fingering, gloves and toys. One time it was a penis size and curvature issue and anal sex was not possible because the pain outweighed the pleasure, but he more than made up for it by how his cock filled my pussy and massaged my front wall....mmmm....but I digress.
I've never had any partner reject anal sex for holy reasons. If they were ever religious, they'd probably figure if they were already having carnal pleasures with a lusty she-demon, what's one more sin regarding a technicality about the hole in which the cock goes?
It's funny that some religious adherents try to avoid the sin of premarital sex by committing the sin of sodomy....shows that silly man-made rules will always be subordinate to nature's rules.
I like to think that the rules about virginity being solely defined by an intact hymen were invented by religious patriarchs whose wives and harem enjoyed anal activity so much they left a loophole for anal sex haha. Being socially pressured to preserve your hymen as a gift to a future husband....fuck that. As for the idea of sodomy being sinful....fuck that too, i like being sinful 😈
