Wine Makes My Lady Parts Whine

Has anyone else ever experienced this problem?  I'm not a big drinker; I don't really like it that much.  But when I do have wine or a mixed drink (can't say about beer cause I think it's gross so I never drink it), my vagina starts to burn.  Just a few sips and a minute or two and that's all it takes for my vagina to start burning with small amounts of alcohol.  My husband says it must by psychosomatic because how could a sip of wine affect me just a few seconds after I've swallowed it?  And I sort of agree, because how could a sip of wine get through my system that quickly?

But then we went to Italy.  I had 1-2 glasses of wine almost every night with dinner and it did not make my vagina burn.  You might think that that supports the psychosomatic theory because maybe being in a different place made me not think about it so much.  But then that last night we were in Italy I had a couple sips of wine and there it was!  The burning!  So now I'm not so sure it's just all in my head.  But I can't figure it out.  There must be some ingredient in some wines and not in others that makes my vagina burn.  It's not a cheap/expensive thing because we always drink cheap wine, here and in Italy.  And it's not an Italian wine thing because I've had wine in America that was imported from Italy.  I've had French, Italian, Chilean, Californian, etc. and they all have that effect.  Why did all the wines in Italy not make it burn, except for the last one?

Does anyone have a clue about this?  So weird.
