At some time I had just the same mixed feelings as you have right now but eventually they vanished. Some people are definitely more exposed to some kinds of medical 'problems' than others that's why prolapse differs in shape among different people. No prolapsed rectum is same as other one. Never.
I had some luck because my as started prolapsing a little early. I guess it was right after I discovered this forum and after 2 or 3 months of progressive play with eggplants, tangarines or bottles. Atm neither am I working on the width nor on the deep but I'm aware of the fact that deep prolapse usually is caused by deep tearing of ligaments.
You are not doing it to soon either, since the tissue which is being hold in place by both adhesive and collagen-bound proteins tends to weaken with age and with work done by your organism. Maybe you just should put more effort into it and eventually you will achieve nice prolapse.
You can also Google some prolapse medical pictures that show a stage called rectal intussusception - the tube into tube effect. If you can recognize this into your own body then all you need is to follow up with pumping and using the soap but if not then I would definitely recommend some extensive anal pushing stretching and putting inflatables into and pumping them to ur limits. The bleeding sign has various reasons but I guess everyone has had a bleeding during pumping. Sometimes it just happens just be sure the bleeding is just a slight bleeding the last thing is that you would want to keep pump inside if you want prolapse and if you want huge lips then you should pump outside your lips. Unfortunately having huge lips blocks the progressive nature of prolapse as it cannot protrude easily.
Wish you good luck!
