Are you self-conscious about sexual partners seeing your anus? Why or why not?

There is a pervasive cultural expectation in many countries that women should be very private about various bodily functions. Women are often embarrassed by the topic of pooping and farting, sometimes even refusing to discuss it or hiding their bathroom behaviors using tricks like running a shower to conceal that they are using the bathroom. There is a half-serious belief by some men that "girls don't poop" because it's taboo and doesn't mesh with the genteel public image of women.

Given this pressure from society, I am wondering whether women are worried about sexual partners (generally male partners, but also curious about lesbian relationships) seeing their anus during sexual activity, and whether it makes them self-conscious that their partner associates it with pooping or farting, and thinking of them in a way they find embarrassing.
