how would they go about this?

what i'd like to know is how they would go about performing this play on stage. i mean did they actually have all of these guys walking around with stark erections? that seems it would be a tad bit awkward. i mean if that was a smaller part of the play they could get away with not doing it but most of the play takes place with these guys all dealing with the same erectile "condition". And then the other part where the choruses were going back and forth with eachother and clothes were being shed during this, would they perform that all in the nude? i'm sure things were different back then because in this day and age that would probably never happen unless it was a porno or something.
