Neil deGrasse Tyson is known to get a lot right about astrophysics and the cosmos, but he's not a biologist, apparently.

On Friday night, the renowned scientist tweeted this:

Washington Post science writer Rachel Feltman pointed out that, although not the case for everyone, sex can hurt for homo sapiens, the same species Tyson belongs to.

Other science writers and biologists quickly jumped into his Twitter mentions to inform him that we're not alone — there are various species for which sex does indeed hurt.

Following the tweet, Wired compiled a list of animals for which sex can be painful. Male house cats, for example, have barbed penises that can scratch up a female's lady bits.

And about those female duck vaginas — they corkscrew in the opposite direction to male duck penises.

As a couple of Twitter users pointed out, some species like bedbugs mate through a process called traumatic or hypodermic insemination, when the male pierces the female with his penis and injects sperm into the abdomen. This creates an open wound that is susceptible to infection.

Nope, nope, nope, nope, nope.
