I'm 42 and been taking 10mg of Tamoxifen for 5 weeks. Recently I stopped having orgams. I don't even feel the sensation build-up that you get before an orgasm. I've read that a dose as low as 1 - 5 mg of Tamoxifen provides breast cancer prevention, and I was thinking of cutting my pills in half to see if it will help. It is hard for me to think of enduring this for 5 yrs. I know I need to contact my oncologist but he is a man and this is an embarrassing subject. I know I should be more worried about preventing my cancer from returning than my sex life, but I consider this quality of life and I have only been married 10 years and this is becoming very frustrating for me and my husband. Any help you can give me would be appreciated.
