Are my P.M Grandis Mating!!??

Please help me guys, i thought they were males but i didn't really know how to sex them when i did so im not sure but i found them this morning like this:

the one on the bottom isnt turned to allow "penetration" but they have been like this for 5 hours or so. I dont see any "penetration" at all by the one on top. If they are mating, please tell me what to do. i have no clue what do do about incubating the eggs or anything, HELP :)

Here's the pic...

Maybe it's just one male being dominant over another? :confuzd: I'm just guessing though.
