Hi,
I think you mean, Oral Thrush. Here's the thing, oral thrush and vaginal yeast infections are caused by the same bacteria ( a candida fungus); there's been a long running debate between researchers and also everyday people like you & me, on whether the same bacteria can be transferred from one person to another via oral sex, mouth to mouth, anal sex, vaginal sex, etc. ~ some say it can be, some still say they aren't completely convinced.
