My boyfriend of 3 years just told me......

..... that he was diagnosed with testicular cancer 6 years ago and had a testicle removed. I don’t know how I never saw that... I know he’s so sensitive down there, after maybe the first 6 months of dating I knew he hated it when I touched him down there so I completely stopped and I never noticed there was only one.... he’s having chest pain and we’re at the ER, I basically begged him to let me go with him and on our way here is when he told me.. we started crying and I feel so emotional right now... I have no one to tell so that’s why I’m on this app....
