What kind of smell is it? I’m assuming not good... healthy healing tissue doesn’t smell like much, so you probably have necrotic tissue. You might need to debride the dead tissue, using some kind of antiseptic solution (like dilute chlorhexadine or betadine), swabs, tweezers maybe. The goal is to remove the dead tissue, that is essentially rotting, until you get to healthy pink or maybe lightly bleeding tissue. You need to be careful that you don’t pull and tear open the healing wound tissue. Your situation is different, but this is a pic of my prolapsed hen. I was having difficulty with her re-prolapsing, and the tissue was damaged and infected. All of that yellow/white in this picture was infected and unhealthy tissue that needed to be removed before she could heal. I soaked her in Epsom salts for 1/2 hr then used swabs to roll away this diseased tissue As best I could until I saw blood, then I stopped, lubricated, and reinserted the prolapse. When she prolapsed again, I did the same again. I had to do this at least 3 times before I only had healthy looking tissue left, then she stopped prolapsing.
