This is the exact thing that has been a long held fantasy of mine. In reality I’m not sure and I suppose in a fight/wrestling match anyone could lose with one mistake. However my gf and my ex weren’t an even match although both were basically the same size physically. The difference being that my ex wanted to fight and did things to bait her into a fight.
At the time I’d broken up with my ex and began dating my gf. So we were fairly new still so had my ex won I absolutely would’ve been affected by it. I know it doesn’t mean anything much in a fight when comparing two girls as to who’d win. The things that I felt an advantage in favor of my ex was her boobs were 2-3 cup sizes different. I know for a fact that it hadn’t really bothered my girlfriend as she would comment about it in arguments. So she was constantly trying to measure herself with her. The other difference was my ex had gotten into a fight before and dominated her rival with the same advantage. That being doubt, anxiety from being afraid to get hurt and losing in front of me since both knew how it turned me on when they would speak of wanting to kick the others ass. In a female fight a lot of girls don’t want to fight period which is understandable with girls. Although I knew Tanya my ex would likely win I’m sure my gf Shannon knew this. Each time they had an altercation I advised her not to fight. So I could tell she thought if it happened I was worried she’d get hurt. Just the thought of knowing my gf was scared of my ex was a huge turn on. I always pictured her pinning my gf in front of me and forcing Shannon to tell me that Tanya was better, stronger. I have no clue for sure if it would go that way. However when one girl has no doubt at all she wanted to fight, while the other was trying to avoid it getting physical at all cost. I’ve written a few stories on here about them and my version of a fight or wrestling match either one. It’s been my #1 fantasy match for a long time. Anyway a long winded comment to say it would definitely affect the way I saw each girl and I’m almost positive had that been the case I’d gotten back together with my ex.
