Do you feel insulted by the idea that you are not "tight"?
Because everyone is a different size. For all sorts of different reasons. It's not an insult or a compliment as such. It just is.
Men like all sorts of different types of lady downstairs, just as women like different types of man downstairs. I dated a man who was very... endowed... and he expressed that some ladies are too small and that he lived in fear of causing pain. Likewise I know women who feel crestfallen when they discover that a man is too large / bends towards their slightly wonky cervix / etc. etc.
I think you have decided that your anatomy is only acceptable if it has qualities xyz. You then asked your husband about your anatomy, but in an open ended way, and he made the mistake of stating a fact when what you wanted was a lie, one that was tailored to salve your insecurities.
It might be better to be a little more accepting of yourself and your body. Vs massively overreacting at your dh for not lying more carefully.
Of course your body isn't virginal anymore, it's actually done things, like have children! Appreciate and love your body for that instead of wanting to deny it.
Perhaps your dh often talks negatively about the changes in your body, and this is the straw that broke the camel's back? If that's the case, then fair enough. But if he loves and appreciates you as a matter of course, please allow him to state facts without getting yourself hugely worked up about it.
