My apologies, but I do not think your beautiful cat could be Ocicat.
First, I think it would be highly unlikely anyone who spent oodles of money purchasing an Ocicat would allow it (male or female) to breed indiscriminately.
Second, phenotypically, I do not see anything in that photo that would lead me to believe the cat has any 'exotic' blood in him.
Finally, genetically, his markings show him to be black based, with agouti and dominant white spotting in addition to his agouti/tabby markings are in the Mackerel-Broken-Striped and almost displaying the Mackerel-Spotted patterns, but since his markings are elongated and not round spots, I am leaning more towards the Mackerel-Broken Striped pattern.
I think you have a beautiful, young, healthy cat with a strong play-drive and hunter's instincts. Cats are naturally very flexible and can/will sleep in some amazing positions in addition to contorting themselves during play and leaping.
I think your cat is a gorgeous tabby/white, which are some of my most favorite markings on a cat.
These are some googled images of Ocicats:
