I have the exact same problem guys. You're clearly not alone. I'm a 28 year old female and almost instantly after drinking any type of alcohol beverage beer, wine, liquor, etc. I get a burning sensation in my vagina and/or rectum. Actually its never lasted over a minute for me. Doesn't occur with a second drink. It's been going on for years. I've mentioned it to my doctor and she's never heard of it before. Kind of dismissed it. I have had too much bacteria and been on antibiotics before which caused cervicitis. I also experience irregular menstrations for the young lady who mentioned Staph Bacteria in her vagina. But you men don't have that issue. As for the guy with the tip of your body like fingers and toes theory its a good guess but us women don't have that issue with our vaginas. Maybe it is some type of Alergy we all experience. Also it doesn't burn my urethra its my vagina so I don't think its necessarily the bladder or prostate for guys. Our urethra isn't connected to our vaginal open its a separate entrance and we have the same symptoms. I don't know guys. I'm stumped as we all seem to be. Thought this info would help. Thanks!
