Panties wet from excitement.

A wet spot on a woman's panties showing that she is so wet that she has soaked through her panties.

A telltale sign that her juices are flowing.

"Tramp stamp in the back, damp stamp up front."
Tommy could see Jessica's damp stamp as soon as she took off her skirt. He knew she was ready for action.
