Why are there pleasure-nerves in the butt? Religion and Evolution both fail 🤦

Why are there nerves in the anus that can feel good and thus encourage anal-sex? Whether you’re a creationist or an evolutionist, there is no answer. If God designed us, then why would he put pleasure-nerves in the butt and then say it’s a sin to use them? If evolution created us, then why would it put pleasure-nerves in the butt when anal-sex doesn’t lead to procreation? 🤨

The only way to explain it is to grasp at straws like “God did that as a test”. 🙄 Or that “evolution did it so that sometimes they miss the butt and get in a vagina instead”. 🤦
