Gina Rodriguez and Possible Fiance Have Makeout Session in Mexico

Gina Rodriguez is having herself one hell of a birthday week -- celebrating on the beach by packing on the PDA with her boyfriend ... or should we say fiance???

Nothing prudish about these shots of "Jane the Virgin" and Joe LoCicero frolicking Tuesday down in Tulum, Mexico. All this fun went down shortly after Gina posted shots of herself with a huge rock on her left ring finger -- so, they could be celebrating more than a bday.

Gina hasn't announced she and Joe are engaged ... yet, but she was still wearing the ring during their wet and wild makeout session. All signs suggest she said "yes."

Fun fact -- LoCicero is an actor too, best known for playing the role of Don Quixote Stripper on ... "Jane the Virgin."

The couple who works together ...
