There's an ongoing debate about whether female "ejaculation" - aka squirting - really is a thing. On one hand, you have people including medical professionals who swear up and down that any "ejaculate" a female produces when she "squirts" during sex is mostly urine. On the other hand, you have other people swear up and down that it is a 100% different substance entirely. Amusingly, this side includes porn stars, who use the reasoning "I've drunk piss and I've drunk female ejaculate and they are two different things". Despite "squirting" being a very popular and desirable component of sex, urination during sex is definitely considered a fetish-only thing.
So I guess what Poliwrath here is trying to say is that she's down with whatever comes out of the cooch.
