things that should or shouldn't be done?

Body: 

I just wondered if walking, sexual intercourse or standing will make my prolapse worse.

No they will not, if you are in correct posture. Walking is especially great. Have you begun to work on posture? Use the search box on here to look for discussions on all these topics, of which there are dozens, probably hundreds! It's all about the posture. Read the forum, read the website and blog articles, watch the videos on the resource tab and on YouTube, get the book and/or a DVD, and jump in. Let us know how you are doing and what other questions you have. - Surviving

I have found that all three actually make me feel better -- as long as I am in the correct posture!!

I just got the first aid for prolapse video. I just watched it. I'm practicing my posture, yes. I hope i'm doing it right.
