Be careful if you care!

I see where you are coming from, but I feel that is a re-definition of the word "vanilla". Going by the Savage Love usage, vanilla is the opposite of kink. No moral judgement, just basically saying missionary is one end of a spectrum.

However, that said, you have an excellent point about how "vanilla" is used on Fakku. Given that we don't have any definitions of the tags, from what I have seen, "vanilla" on Fakku is if something is loving and sweet. There was a "vanilla" incest story a while back.

 I can't speak for others, but I think any anal play is a kink, regardless of gender, but I feel out in the wider world, there is homosexual subtext with with male anal play (i.e. a fear of gayness).

Well, Vanilla doesn't infer if the content is sweet or loving at all. It just means it isn't on the extreme end of expectations for sex. I'd say expecting your partner to take a dildo (or even a penis) in the ass is pretty far on the extreme end and far enough away from "vanilla" to exclude the tag. I'd say the same if it were a female getting anal as well, though pegging does tend to get put into a bit more extreme a case since it is the penetrative partner being penetrated which is a pretty big reversal of sexual expectations.

I don't know about "fear of gay" but I in general fear things going into my backside. I had a probe up my rear for a medical exam and that shit was uncomfortable and at times painful. Not a sensation you forget. Guh... *Shudder*

Hehe, You said butt pegging.

Dude, I totally missed that! Thanks @Thealas
