I bought an over-the-counter treatment for a yeast infection and applied it last night, but when I woke up this morning everything "down there", especially my labia minora, was swollen and red. It is tender to the touch and burns. Is this because of the treatment? Help!

ive had a yest infection before but this one is different i got the itchy and the irritated part of it as well as the white discharge but now i also got this type of sore that burns when i urinate. Can this happen with a yeast infection? or does it sound more like genital herpes?

Im a 21 year old guy who thinks he has a yeast infection. My gf recently had it and we had sex the day she realized she had had it. Now its been a week and I barely got this rash under my penis, it burns. Im asking what are some cures to cure yeast infections for guys? Can I use vagisil?
