text: after drinking alcohol, burning sensation after ejaculation.? i have a question that has been bothering me and actually a couple of friends for a long time.  this only happens when i am drinking alcohol.  anywhere from 2 drinks on.  if i have sex about 5 minutes after ejactulation, i start to get a horrible sensation in my penis.  usually towards the tip.  it feels like i have to pee really bad and there is also a lot of discomfort.  discomfort could be similar to a bladder infection.  it does not stop. i feel like i have to pee so bad, and i go to the bathroom, then 2 minutes later it is the same thing.  i am sure that it has something to do with the alcohol, but i wanted to see if there was anything i can about it.  just so you know, i have been tested for std's and have been clean.  this has been going on for 4 years.  please help if you can. if your bother comes during the daily urination act too, it will probably be an infection of the urethra.  on the contrary, it could be a prostate inflammation or a shorter “frenulum” even. [the prepuce is usually tethered at the bottom by the frenulum]  at last, we should consider the vagina environment too, whose infection or acidity could be another cause.
