Catholic theology of sexuality , like Catholic theology in general, is drawn from natural law ,  canonical scripture , divine revelation , and sacred tradition , as interpreted authoritatively by the magisterium of the Catholic Church. Sexual morality evaluates sexual behavior according to standards laid out by Catholic moral theology , and often provides general principles by which Catholics are able to evaluate whether specific actions meet these standards.

I thank God I was raised Catholic , so sex will always be dirty. The Catholic hierarchy is obsessed with sex: who does it, when, how, with whom, and for what purpose. In fact, I might argue that one way conservative religion hooks people is by creating psychological hang-ups about sex, for which it then claims to offer a solution. The Church knows that. It also knows that forbidding something we crave—making it taboo—can make the craving stronger. Even if you are secular you likely have been infected with noxious ideas that come straight from the Ancient Near East and Medieval Europe by way of the Catholic Church or derivative Protestant sects. If you want to live by your own values when it comes to sex, it might help to ask yourself which of these ideas and messages have gotten inside you in some form—and then check them against reality.

Anal sex is is really unhealthy. On moral issues, Catholicism follows a principle known as Natural Law. There is an unnatural and disproportional disparity of power between a couple during anal sex. Throughout history it has been more about power than love.
