1. it takes usually six weeks for normal but may be tonger with a rip.
2.it doas not feel less sensative but it might feel soar and tighter but after a couplr times it feels normal.
3.yes you do feel a size difference because before i had the baby i was so very tighteven to tight for him and know he says its better. so it doas change but not to much but you might get air in their and then when it comes out it sounds like a fart its emberassing but it goas away in time
