(NSFW) Why is it TV shows will show a fully nude woman but not a man?

This winds me up no end.
For example I was watch last night ‘Strike Back, Project Dawn’, in it there are some very nude and graphic shots, but they all involve women, fully nude simulating sex.
There is the odd shot (fleeting at that) of one of the leads bottom.

Now this annoys me no end. I don’t mind watching the odd scene with the naked woman (its not horrible) but, let me turn this on its head, guy’s how would you feel if you watched a really cool show, but the essential sex scenes were all fully naked guys and the odd female bottom?

I know its illegal for the broadcasting standards agency to show a fully erect penis on terrestrial television, but its not for a non erect.

So where are they, where are all the naked men. Whats wrong with these producers. Some women may be too polite to say anything but I am not.
I stand here and say “I AM A FULLY HETRO-SEXUAL WOMEN, I THINK ABOUT SEX, AND ENJOY SEEING NAKED MEN, JUST AS MUCH AS MEN LIKE LOOKING AT NAKED WOMEN. ITS JUST AS NATURAL FOR US ( no matter how much we protest we do!!!)

So where are they, why don’t we get to see them? Anyone enlighten me on this?
