1. All depends on the style of the fight. If it's a street fight no she couldn't. If it's a grabbing contest with very specific rules then yes she could. I'm a poor wrestler and despite how my strength due to working out 5-6 days a week, I tire easily (I'm a weight lifter who doesn't do a lot of cardio). So if she is highly skilled and has a big tank, she could beat be in that situation.
2. On our feet, my strength and striking would beat her. But on the mats, her skill, speed and stamina would kick my ass.
3. She could knock me out. Either choke me out as we're grabbing or as I'm too exhausted to continue, grab me by the hair and pull me to my knees and bash my face in to I go nightly night.
Regardless I have a raging hard on the entire time and be more then willing to worship her muscles postmatch whether I win or lose.
