Do you play fight and have pillow fights with your guy friends?

My guy friend recently started play fighting with me. He thinks its funny to douse me with water, throw me in pools, hit me with pillows, body slam me on the bed and punch me in the arm. I have no clue what he gets out of this because his fights are often one sided and he rarely lets me get a hit in or any retaliation. He really enjoys it and I have no idea why.
