I am dating a guy who has very large testicles, almost the size of a tennis ball. He also has not been able to get hard enough for sex. I have also noticed that he uses the bathroom frequently. I'm not sure what this could be. He told me he thinks it is because an ex-girlfriend made him use viagra several years ago when he did not need it. This explanation really doesn't seem correct to me.

I've tried to find something with all of these symptoms online, but have had no luck. Any clues???
