He did use that word, but I wouldn't be surprised if I'd used that word with him at some point as well. I feel maybe it's more common in the US? I mean, I use it at times (though...I don't know, is that different because I'm a woman?) I didn't personally feel offended by it because of the context in which it was used. And in terms of cursing, I didn't include this in the writeup, but I used the F-word like 5 times that session, to the point that I said at one point, "Wow I'm cursing a lot today."

I'm not sure I see the blue balls as necessarily being particularly sexist, as he said it's not like H was dealing with that effect. He wasn't all "Oh, you're giving him blue balls!" He was supportive of my being in control of how often I want/have sex and basically being like, "Eh, H will be OK, he can take care of himself." It would be completely different if he'd acted like I owed him sex or something.
So I can see where it would offend some people, certainly. And it might be different if I'd just started seeing him. But I feel we're at a point in the relationship where I've shown to him (again, partly by things I've also said) that I'm OK with it. Should some of those words maybe not be part of the language in general? Sure, OK. But I feel in the context and limited times my T uses them, it's all good. If others would choose not to see him because of it, that's fine, then don't see him.
