I wish there were a term for the fallacy of writing off a declaration of fallacy as a discussion-ending repudiation while at the same time accusing the declarer of misconstruing one's own supposed concerns as a discussion-ending repudiation. (Moral: this is getting a bit ridiculous, so let's keep the discussion on the level of, well, the discussion, rather than talking about the discussion, or talking about talking about the discussion, etc.)
As I have mentioned several times, thigh_sex has other problems, such as its dissimilarity to other more common tags describing the specifics of sex acts, which generally tend to take the form of an adjective which could modify "sex" or "intercourse" or whatever - for example, vaginal, anal, oral - as well as its ambiguity (e.g. it ignores the "inter" part of "intercrural").
I see nothing wrong with footjob or handjob. I accept paizuri because the only English alternatives I know of either are far from voiceless ("tit fuck" or "titty fuck") or sound ridiculous to me (Wikipedia's "mammary sex"). "paizuri" is pretty good, actually - it's relatively voiceless, being a simple contraction of "rubbing with/of breasts" - the only possible problem is that it's in Japanese, which is kind of unintuitive to most users of the site (though some have argued before that the userbase "should" be more acquainted with japanese terms).
EDIT (2): Before someone accuses me of being hypocritical finding "mammary sex" ridiculous but "intercrural sex" acceptable, let me point out that "intercrural sex" means exactly what it looks like - "sex between the thighs" - whereas "mammary sex" doesn't seem to be literally meaningful at all. You could argue that "mammary sex" seems to mean "sex related to the mamma". But this is less precise than paizuri, not to mention that the primary erotic focus of a breast is not its milk-producing function, which is highlighted in the words "mammary" and "mamma". Just a little introspection there, haha.
Any other ideas for tags to change?
EDIT: Oops, forgot to address a couple other things you said. First, about the aliases: I don't see pretty much any of what you mentioned being a major issue. Yes, aliasing A to B does constitute an explicit endorsement of B over A. My point was not that A and B would become interchangeable - things like not being able to add A to the tags list using the +/- links all contribute to the endorsement of B. I don't know how autocomplete works (I don't use it) so I can't comment on that. The others seem to be design quirks which can be ironed out, I think. But anyway I'd like to think that I am giving reasons for these aliases. It's not like I'm saying "aliases are fun, let's alias these just because we can." I've provided what I consider solid reasons for these aliases.
And as for your comment about the OP, I suspected I was overthinking it, and thus qualified my statement in my previous post. Glad to hear that you didn't mean what I feared you might have.
