Patrick Schwarzenegger -- Ripped ... For Her Pleasure

The ladies LOOOOVE Patrick Schwarzenegger's body ... especially his nipple?

Arnold's 19-year-old kid was hanging out on a yacht in Saint Tropez with his girlfriend Taylor Burns ... when she decided to play the role of male breast inspector.

Meanwhile, over in Hawaii ... Eddie Murphy's girlfriend Paige Butcher rocked another tiny bikini.

Happy summer everyone.
