NTA.

I had to have a hysterectomy at 33 when my youngest was shy of 1. It was hell and like you OP, I felt less than a woman.

My husband and I were having other marital problems but he didn't want anymore children and I still wanted one more but knew my life would be in the balance if I did.

OP.. please look into counseling for you both. Obviously there is more to this than your story, but it sounds like you and your husband need to resolve this issue a about children.

My husband takes viagra also. It's common for men in their 40s to have some issues. Your friends are well aware of your issues with pregnancy, so your husband's comment was directed at you. You said your friends are not aware of his prescription, so your comment was generalizing.
