Is it true that testosterone fueled Male "contact" sports attract mainly "gay" participants and spectators?

Very probably, particularly here in America where homosexuality is latent within the Male community.

It has to do with the isolationist nature of communities and landscape.

Men just feel more at home with their horses and other men, out there, alone with each other, curled up side by side around the campfire.

It's no wonder they make such lousy lovers and when forced by a marriage they undergo to keep their guilty life secret, they like to be rough with a girl and hurt her.

That's why most American girls favour British or continental guys.

They know how to treat a lady.

So, keep to your football and that other penis substitute, the gun and go play with yourselves!

Yes. All 80,000 fans packing the stadium for a football game are gay, as are the 22 players on the field, the officials, coaches, waterboy, et al. That's why I watch.

If that were true figure skating would be the most popular sport.

No, but sports like rugby are extremely homoerotic.

And gay men love to watch masculine, athletic men touch each other and get very physically intimate.

It's hot.  

If that were true, I'd go to a lot more male contact-sport sporting events.
