If it's used humorously, and only occasionally, it's OK. If crude slang is used in the review extensively, it bothers me. I like the word "cunt" "pussy" "cock" "dick" during sex, but I really prefer the actual terms for the word, vagina, labia, clit is OK, you don't have to spell out clitoris, unless you want to, penis, testes or testicles (even thought the proper plural of testicle is testes testicle is just ONE, I am not going to hold that against a writer, because everyone except English Majors and offspring of Technical Writers (me) use "testicles" for the plural. It doesn't bother me at all. (But the proper work IS "testes.")
I think most of the time, unless the words are only used once in a while, or to make a point or to be funny, it's OK. Seeing a review where the vagina is called a "twat" or a "fuck hole" EVERY TIME they mention the vagina just makes me think the reviewer isn't taking is as seriously as he or she could or being lazy.
But, occasional use, is fine. As most things, context and intention is everything.
