Changes

So I've noticed some sizing changes down there. I know not all can relate to this, but the dildos and strapless strapon (woman married to a woman) that I used pre-pregnancy no longer fit. They can kind of go in, but it's pretty uncomfortable. I'm sure this is because of my uterus changing and the baby growing, but it's making time in the bedroom uncomfortable for me and my wife. I think we're going to seek out modifications, but what I want to know is after I have the baby, does everything go back to where it was? Like is this temporary or am I now just changed? I'm not looking for commentary on my sex life choices, just what's happening/going to happen to my vagina.
