This might sound crazy but... TMi btw

I've been married for a year, been with my husband for 3 years. We've both been tested &I are STD free. I've had a few bacterial /yeast infections over a few years but nothing serious. It's been at least a year since I've had either one. Well, the other night he had just got out the shower and we were getting ready to BD & I noticed a really bad smell on his penis. Similar to that of BV. I asked him what was up and he was like idk I haven't noticed anything. He's circumcised so it's not a hygeine issue. Same thing happened the next night , fresh out the shower. But it's not like that now.. I haven't really said anything else to him about it but I've been kinda worried. Would it be wrong for me to go get tested without telling him ? Just for peace of mind.  I've been 100% faithful but I don't understand how he could have gotten a bacterial infection from me when I have had absolutely no symptoms or anything. Leading me to think it may be Trich, or whatever else. Just wondering if anyone thinks I'm over reacting , save the rude comments for someone else please
