I can see why you would resent use of the word oblivious. Perhaps it wasn't the right word. After all, you admitted in your first post on this thread that you were aware of Prep but didn't take it. So let us consider your actions. By not taking precautions you became infected with HIV and, by your own admission, had unprotected sex with many men...who knows how many you infected. You also claim to love Brazillian men - what is your definition of love? Mine includes to care and to protect. That includes to care about, and to protect from HIV.
Perhaps a better word is 'selfish'. Or perhaps 'irresponsible'. Maybe 'uncaring'. I am not trying to be harsh, just keeping it real. Your actions have consequences.
