No image search match but I think this is Picasso.
I was thinking about how he really "commits" in his art, like, everything seems to be just as it flowed out from his hand, no second-guessing, no forethought. The first pass is exactly what it should look like, and then he continues from there. I don't know if that's true but that's the impression I have. Maybe there's some sexual imagery but I think mostly it just seems fun and alive.
