I believe that when the boy faces the girl on the mat, in any position, he is more worried about losing than sexual interaction. If he has trouble with that, what does it say about him as a boss who has women as subordinates.
Look, I understand both sides of the argument, lack of girl programs tanking the boy’s programs (completely bogus), women in men’s sports (but no men allowed in women’s sports), religious convictions, etc., and in many cases, it might occur where certain wrestling interaction appears beyond the rules. But that can occur in all sports coed or otherwise.
I guess the general notion that girls should not compete in the boy sport simply because the boy might get aroused, have a fragile ego, or errantly/intentionally make questionable contact, are weak positions. Been fun.
"Errantly/intentionally" make questionable contact??? No, I don't think you ever wrestled. There's no choice but to grab her chest and crotch or inner thigh and then, with all your weight drive her face into the mat. She'll, of course, be doing the same thing to you if she can get an edge.
Perhaps neither of you will consider this sexual but how will the parents and students watching consider it?
Or, maybe worse, you can, from the bottom position, execute a sit-out and switch, driving the back of your arm into her more fragile shoulder joint, possibly doing real damage. Normally, this wouldn't be dangerous for wrestlers in the same weight class. But a woman's upper body is in a lower weight class than her hips and legs.
But later you can always go out on a date together and grab her chest and crotch and get slapped or arrested.
The poster, above this, who responded to your post hit the nail on the head. Wrestling isn’t like many other sports. Even football there is equipment over body parts. Like I said, I don’t mind playing sports with girls. I just don’t like playing competitive sports with girls. It’s just not the same in any aspect.
