Well, first I should correct my statement by saying that one should never "react" but rather choose to "respond". Then my answer would be that he stated his opinion/preference in a manner in which he did not make himself vulnerable and therefore he chose to make himself offensive and disrespectful and I should have "responded" in a manner appropriate. I believe in "brutal honesty' but I think the one you should be brutal with is yourself. Expose your own wants and preferences and vulnerabilities. Don't attack the other person's in an effort to bolster your own. If I had to do it all over again, I never would have stated my opinion that my 2bx had a low sex drive, instead I would have said "I am a greedy, horny girl who wants lots and lots of sex." and let him sort out his own preferences on the matter.
