Re Chrom
the link it might be helpful. Thanks.
www.Goodvibrations.com and http://www.soulsourceenterprises.com/ has larger ones . Lots of 5"L and 1.5"D found by Googeling.

Your W does not have the medical problems associated with painful intercourse but here are pages that describe some procedures and usages of dilators.

These are cancer web sites where I have looked for information. Actual women with the problems post on some of these sites so there are suggestions to what works from users and sometimes MD type replies.
I am guessing if women with medical problems find some relief, your W w/o the actual medical problem should benefit.

I have looked at web pages that are similar to the fat burning pills sold on TV. I don't trust those recommendations or advice there.
