Both of my boys Colby and Levi will drool when I just pet their heads. I don't even have to massage them. Pearl loves me to tap her back end on both sides and rub it. She goes crazy and she then starts talking to me very loudly. If I do it too much, she'll get nippy because it overstimulates her. Blaze loves for me to rub his cheeks. He'll then start head butting me. The rest of them like head, chin, and cheek scritches. Sky also loves me to scratch him near his tail. He'll then do the elevator butt. I used to massage my RB Storm and he loved it.
