Nope...sorry...does not compute.Can guys be sexual "pigs"? Yah.More than a few are unfaithful and many of those who aren't are at least tempted.But if you're "doing" one or more women you *do not* turn around and start doing boys at the same time.Can such a guy be sick enough to "do" girls at the same time? Maybe.But not boys.
You are talking about things that are only sins in our Judeo/Christian culture. The rest of the world believes differently. This is our future as we leave Christianity behind.
