Is it normal to throw semen in my dogs face

everytime i masturbate i collect the semen in a cup and call my dog to my room, from here i like to empty the contents onto my dogs face and continue to lick it off, a few times during this i have had the urge to have intercourse with my dog it happend once but my dick got shitty while i was washing my dick my mother walked in and i had to tell her what happend. anybody else ever done this???
