Labia: The Guards At The Door
Folds of erectile tissue that together make the vulva and guard the entrance to the urethra and vagina. The urethra is situated just above the vaginal opening, which makes it easy for bacteria to be pushed into the urethra during intercourse--causing those aggravating urinary tract infections to occur and sometimes recur. Drinking lots of water--or cranberry juice--can help prevent these infections.
