Rolly Romero's making it clear it's totally fine for men to cry ... and he tells TMZ Sports anyone who's making fun of Ryan Garcia for his emotional outburst after their fight last week can go pound sand.

Rolly Romero has revealed the one fighter who has hit him the hardest during his career. The 29-year-old from Las Vegas, Nevada produced a disciplined performance to defeat the returning Ryan Garcia at the iconic Times Square in New York City on May 2.

Romero scored an early knockdown in the second round before cruising to a unanimous decision win over Garcia, who was fighting for the first time after his one-year suspension for testing positive for Ostarine following his win over Haney that was overturned to a no contest.
