Women can indeed give men their yeast infections, I should know, it happened to me for a while. My girlfriend from a long time ago had a real bad yeast infection and was fighting it, we had sex and I went to sleep, not thinking it would harm me. Well just rolling over and going to sleep with that funk on me, all warm, and dark, it settled on my upper thigh, like where my stuff would lay on if I was on my side. It presented itself as an EXTREMELY (I mean rediculously so, worst itchiness/tingling/I must scratch it I have ever felt) itchy/tingly red spot about the size of a quarter.
I didn't connect her yeast infection to it, and just thought it was something weird. Well, us guys tend to scratch our jewels often, and apparently I had scratched the red spot a ton and then scratched my scrotum after. It then appeared on my scrotum. After a few days my entire scrotum, a large part of my upper right thigh (nearest my groin), and even my upper left thigh (near my groin) were all fire engine red and ablaze with agitation. I went to see the doctor and he asked me questions, and I told him about her yeast infection and us having sex. He told me that guys can indeed get yeast infections, but instead of internal with women, it's external (few layers of our skin), and can be much worse than what they go through.
He told me to just buy some over the counter yeast infection creams women use to fight it. I did that and it helped, but what we were doing was cross infecting each other due to sex, over and over. Finally we abstained and went nutty with the creams, and it went away for both of us.
So technically, that's my one and only STD I have had. So to answer your question, hell yes guys can get womens yeast infections. If you get a yeast infection, spare the guy a giant chunk of potential misery and don't have sex till it's gone!
