CATON: Consider this... During a wrestling match, adolescent males are contacting each other in ways that would MORTIFY them in a different setting. And I can just about guarantee that male-male sexuality issues are a much bigger bugaboo for them than male-female issues.
I would agree with you about the issue of protective-towards-females conditioning...up to a point. When someone has you in a head-lock and is squeezing off your air, I would be willing to bet that their gender is not your immediate concern..
Bottom line: during hand-to-hand combat, sexual issues are not foremost in the mind.
