A great Edo Period shunga woodblock print picture of a stressed-out male lover tyring his best to get hard for his female companion.  At the moment he's simply rubbing against her, which is working for now, but his seriously determined look and clenched fist indicate that it's going to be anything but an easy roll in the hay.  Good luck, friend!
