Ronda Rousey ain't ashamed to say it ... she's all about banging dudes before she steps into the octagon -- thereby cementing her place as the coolest chick in sports.
The MMA champ revealed her pre-fight sex rituals with Jim Rome on Showtime ... saying, "I try to have as much sex as possible before I fight, actually."
Rousey says the old theory about no sex before fights doesn't apply to female fighters because making the beast with two backs increases testosterone levels in women -- clearly a plus before brawling.
TMZ broke the story ... Ronda is jumping to the UFC to become the league's first female fighter.
So, who are the lucky guys sparring with Ronda ... horizontally? We'll let her explain ... sounds way hotter when she says it.
