As biased as I am (very), I'm not sure how this applies, none of the library names I know suggest anything sexist, or otherwise offensive.
Now, as for whether naming libraries after sex acts, and possibly body parts, is a good idea, well, does it matter? Worst case it makes your conversations more fun.
Asking a co-worker about the AnAl library could elicit a chuckle, or it could be an example of what alienates female programmers from the game industry. It isn't inherently a big deal, but in the hands of the immature and can easily go from funny to uncomfortable.
If the sexual funniness stems from the library the team is using, then the awkwardness can be addressed in a team meeting well in advance. Perhaps resulting in a only-one-joke-a-day policy or changed pronunciation (e.g. AnAl like "analgesic").
