After delivering (vaginally)

Did you bounce back I heard some say they became tighter? .. I’m 19 I had my baby 6 months ago & I just don’t feel like I feel the same or if sex will ever be the same.

My cousin made a remark that upset me a little she said “I’m glad I got a c-section least our vaginas are unaltered.” “Yeah once you deliver a baby vaginally it never goes back.” That comment made me self conscious..
