Im Looking To Get A Rosebud, If You Havent Heard

im looking to get a rosebud, if you havent heard of it it is essentially a minor anal prolapse where only a small portion of your rectum sticks out of your anus, im looking to get this only to try it because my friend who did this and had it played with and licked ect. said it feels amazing, so thats my reasoning, i understand the possible dangers but im willing to risk it, anyway is it the case i just need to have rough anal or do i need to do it for a long time, or do i need to actually go big and stretch my anus? im not sure but want to know, any help would be great!
