that odd advice smells strongly of stupidity in my opinion. sex is important in a relationship for intimacy but sex will not "clean the uterus" or prevent the spread off early uterine cancer. your wife needs to get a second opinion from a ob/gyn specialist and you need to go with her to hear the advice.
i was just told to have sex with my wife to clean her uterus. she complained that we didn't have sex and that i didn't want anymore children to the doctor. she has problem with her uterus and the only solution is surgery or to clean her uterus by having sex this is what the doctor told me. the doctor also told me that she had the beginning stages of uterine cancer and that i have to have sex with her so it doesn't spread through out her body is this some kind of joke or is it a fact
