I found out 4 months ago that my husband of 21 years has been having an affair for 18 months. Afterwards we started having sex again. His sex was unprotected. I have since had numerous female problems. Can someone please help me. I am scared to death. Right now I have numerous knots across my stomach. I have pain and also UTI's and bladder problems. I've never had these problems before. Could it be that my body coud not fight off something he has given me. I am so depressed. Please help me.
