I've noticed that too about mine. We usually do it at night after I go to bed but if I get home from work and am sweaty or come in after a run, he'll start nudging and sniffing me like he wants to go.well nighttime usually when the bf leaves for his nightshift.
Or...after I get done at the gym...before I shower. He loves the scent
If we miss a night or two and I have the next day off, we will have marathon sessions where I will put 3-4 loads in him too. Love those days!My boy usually takes a load every other day or so and up to four or five loads in a single day if I'm pent up.
