That's like asking the guys if they'd want to talk to the guy their GF had a one night stand with. I know that most one-nighters are usually not that memorable. It's just sex and then goodbye. I'd have to say No.
YEAH, while I'm at it why don't I ask the first girl he gave oral to too and ask her how that went. And the girl he lost his virginity to, and geeze the 1st girl he kissed.
Why don't I size myself up to all these 1sts in my man's life so I can obsess and wonder and freak out over nothing.
Why? So you can torture yourself? You need to let it go or move on to someone you can trust. In the end you will do what is best for you...trust your own instincts..
Um NO.... Seriously are you for real? As long as you got tested, that's all you should be concerned with. And if he cheated on you for a one night stand, leave him.
