Why do you feel horny when you're drunk?

human beings are primarily primates with a fairly constant desire to mate-whether to breed or not. the only reason we dont jump each other's bones all the time is due to a certain part of our brains advanced to supress these desires. drinking alcoholic beverages leads to a gradual incapacitation of said part,a condition known as intoxication(read drunk) ergo the horny feeling previously mentioned.
