Oral Sex - Signs of infection in mouth

My wife is not aware of this, but I have had a few encounters with women I have met over the last two years. I had 3 different women perform oral sex on me, all claimed to be clean. It's been several months that I have been loyal to my wife and no longer will seek private encounters. I have no real signs of infection on my penis, but my wife lately has had canker sours in her mouth every now and then. I am hoping it's just canker sours which I know are common. My wife is my only partner now, and she performs oral sex on my regularly (as often as once a week if not more). Any feedback would be appreciated.

Overall the risk is possible but low. And if the canker sores are normal for her then I would not give it a second thought. And without you haveing any symptoms chances are very low that you got anything.

So you just met these women for oral sex and nothing more?
