Husband's comment about my body...

So this morning, my SO & I had just finished having intercourse & we were just laying there when out of nowhere, he says "Is there a way your doctor can make your vagina tighter even if you've had a C-section?" & I was shocked. We have a 3 year old born via C-Section & now I'm 17W4D with our second, who will also be via C-section. I told him I didn't know, that kegels help but that since the vagina didn't actually push a baby out, that the doctor wasn't going to like... put an extra stretch down there! I immediately got out of bed & have been in my feelings ever since. I'm only 22. He is the only man I've ever been with. So he's basically stating that I wasn't "tight" anymore which hurts just as if I were to tell him he has a little dick. I just needed to vent. Pregnant hormones are blowing this out of proportion.
