Oversharing about Positions

Ok, so a few posts back I made an offhand comment about trying to find a gay kama sutra... now I'm not trying to burn up the world here but it's just... I can't seem to do the "cowgirl", er "cowboy" position and it's frustrating me. The first time I tried it, it was just incredibly painful, and the second time I just couldn't seem to get the position right.

Like... where am I supposed to put my legs/feet? I don't think I'm doing it right.

The other positions are working fine, this is just one that is eluding me...

OK, I feel awkward now.
