i was thinking (and i swear he could smell my thoughts) how, since a dog like him was neutered, he didn't have sex, though he could have perhaps, he always got a boner when he felt good, but maybe he wasn't ruled by sexual desire, like hunger, and so his desire was sublimated, and so he loved life. of course you can have sex and love life generally, but sex tends to individualize, maybe serially, and there's a certain narrowing of scope. he did hump his pillow bed, and he quite often got pink erections posing for me. once when he was young and he smelled bonnie in heat he did think of sex, i could smell his thoughts and saw his thinking body move that way, but then he kind of blanked, forgetting what he was thinking, and just smiled away.
