IAmA girlfriend to a man who battles testicular cancer

I am a 21 year old who had a serious, extended relationship with a man who battled testicular cancer and faced a critical removal surgery. He has just been re-diagnosed. I won't answer any questions that reflect negatively on anyone, just trying to help out anyone who may have questions pertaining to the subject. I don't expect much of a response, besides maybe helping one woman or man feel confident on the subject
