Here is another question for the GG.

Why is it these poses are necessarily feminine, and meant to attract men.

Why are men limited yet again in another field of expression?

Why can men not pose provocatively or sexi?

As I have stated most male poses deal with the display of power, or brawn, or strength....notice, how all of those have a key feature, I will leave it to the reader to figure that one out.

My "sassy" pose, is in fact a "manly" heroic pose, not much different from what Superman is regularly seen doing. Standing up with arms crossed at chest is also a heroic pose, more like one Batman does.

Once again, the line between male and female is razor thin and easily transgressed.

The pose of the subject lying on one side or the other can be taken as a submissive pose, and consequently feminine. Once again this is a social construct that can easily be shattered.

Now, that is not to say there are poses that are very "feminine" and that is because they emphasize something only women have...breasts. These poses are done by us I think because we are trying to appear as feminine as our bodies will allow, though, when I am in androg or male mode, I am known to use such a pose. The afformentioned superheroes are also known to do this pose.

It is all silly non-sense to allow yet another area of limitation for men to remain.
