Gary Shirley Dropped $5,000 on 11-HOUR Stripper Bender

"Teen Mom" baby daddy Gary Shirley went on a MARATHON strip club session earlier this summer ... TMZ has learned -- dropping $5,000 on 11 hours of boob-filled butt-flossy awesomeness.

We're told Gary made it rain at a 24-hour gentlemen's club in Miami -- unleashing a constant stream of cash from 1AM to 12PM. Count 'em. ELEVEN HOURS OF STRIPPERS.

According to sources inside the club, Gary kicked off the evening in the VIP area -- and then moved the action somewhere more private ... the champagne room.

We spoke to Gary, and he had no comment.
