Question for natural birth mothers? Help!?

I need to know if after having your first baby naturally if your vagina elasticity and your sex life/pleasure was ever really the same. What age/health conditions did you have?

I tried talking with my husband about the future. We agreed on waiting a few years until we have our own house before having kids, to have one baby naturally and adopt one(if all goes as planned.) I know it's so far away to be worrying, but all the sudden I have a lot of fear and anxiety about the state of my vagina post birth. Will it ever be tight again? Will it affect if I or my husband are able to experience pleasure during intimacy? I tried voicing these concerns to him and naturally he assured me that he would love me no matter what, that he is committed to me no matter what happens to my body, but I voiced my concern of the possibility of never being able to feel much pleasure during sex afterward and he basically, not in these words, told me that I would have a baby after to numb the pain and that is a normal female human function and tons of women have done it and survived, though not the only function, but that doesnt answer my concern whatsoever. The more I voiced my concern the more frustrated we got and basically accused me of not wanting to have kids as I promised and assumed that I will hate my baby because of the damage to my body which never came out of my mouth from voicing the concern?!

I feel so depressed. I know he isn't meaning to hurt me but I feel like if he asking me to bear his child the least he can do is listen to my concerns. I just want to know that I won't lose pleasure during intimacy and be a permanately saggy roast beef sandwich.

He doesnt want to be near me, and he wont give me the intimacy that I crave tonight because of our fight. I feel so depressed, I just wish he would understand where I'm coming from. I hate communication issues.
