Can the vagina be tightened to normal

After 4 kids, 1 cesearan, 3 natural, with no tares. No stitches, and loads of keegals, will my vagina be able to go back to its normal tightness again. And feel normal during sex, my partner now ex, use to keep me going I was wide etc, it really knocked me. Now I'm single and paranoid incase it feels wide.
