Male doctor pressing my wife's breast

Yesterday I had to visit the doctor for my wife with some pain on her b******. In the clinic she had to remove her top and bra. With his gloved hands the doctor pressed her bare b****** in my presence and I could see her nipples hardening. Seeing some male pressing my wife's b****** my c*** got hard with an excitement as he was testing. I checked whether the doctor is also having and hard c***. But in his gown it was not clear. I thought if it was gyno and he had to check her p**** what would be my condition. I may have c** in my pants. Have any one had such experience ?
