Disgusted with SO

So I recently moved in with my SO. He was coming back home late for work. There's these drawers in the bedroom that he said that he needed to still clean out for me. 
I decided to look inside the drawers while he was still at work. 
I found empty cigarette cartons. He quit smoking 2 years ago but the cartons don't look that old. So now I'm questioning if he even quit. 
 But that's not even the worst part I found OLD USED CONDOMS. The semen inside the condoms started to turn brown. How nasty is that??!!! I was so disgusted with him. 
Would it be wrong of me to say something to him even though I invaded his privacy???
