I have a 4 year old, (who spends alot of time in a bathing suit..) and he was itching his penis tonight. He did say that it itched, not hurt. I noticed a couple of red "dots", but nothing that looked like what I've seen before. Can boys get yeast infections aside from diaper rashes? He is potty trained, so doesn't wear diapers anymore. Also, if it is yeast, is it contagious? I've had them before, but I knew enough to wash my hands continually, etc. Help!
