E.M.
I used to have problems with this, but it has decreased over the past couple of years.
My doctor perscribed an estrogen cream that is applied topically to the area affected, and it greatly reduces the pain during and after intercourse.
Also, and I appologize for the graphic nature of this statement, I found that using lubricants like astroglide, etc., made it worse and that saliva worked much better. For me, having enough lubrication was essential.
Hang in there, I know how hard this is, but there is hope - mine is gone now.
