First of all, by “explicit contents” I really mean the that thing.
In Shakespeare's play Julius Caesar when Brutus had planned everything and the night before the assassination he was in his room he had a little conversation with his wife Portia. During the conversation Portia says
Giving myself a voluntary wound
Here, in the thigh: can I bear that with patience.
Why we got such an explicit reference in between such a serious and intellectual scene? Why writers put those things in plays which shouldn’t contain it (in my opinion).
I got one more example (suggested by @Rand al’Thor) from Romeo and Juliet, Act II, Scene IV we find
"the bawdy hand of the [clock] dial is now upon the prick of noon".
Please understand that I’m not criticising any playwright all I want is to know why it’s important to make such references when things are better without them (in my opinion).
DEFENCE: Users are asking me to clear out what I think about “thighs”, well (@MattThrower has pointed out) it is “thigh” which is used in that verse not the “thighs”. I think the word “thigh” refer to something explicit or as something pre to reproduction act because a women don’t talk about their body parts which are close to genitals (as far as I have been around with relatives or acquaintances) and “thigh” is quite close (near) to it. The problem is why would a woman inflict a wound on her “thigh” rather than on any other place, what’s the significance of “thigh” in that verse.
