I mean, I think it was certainly in bad taste and a bit crass. Not something I'd expect to be banned over. But honestly it's not even the mention of genitals as such, it's more the idea of not standing the sight of your own. While probably a joke, it's also a bit TMI. I suppose I could understand someone feeling uncomfortable about it and if that's something the server wants to curtail, I suppose they are free to.
I do not think you were banned due to not wanting to date men, but rather giving too much information unwanted about how you view your genitals.
