My boy had a several ways to catch my attention - either he was just fixed his eyes on me without any particular movement, and peerced me with somewhat happy but lewd look. It's hard to explain, but there just was one type of facial expression that he used for that

Or he provoked me to a play, in which he was becoming more and more dominant, then trying to kiss me and lick me, trying to get me into the right mood as well

Or, when I was lying prone, he would lie with all his body on my back, poking his nose into my neck and head, tickling me

Or, he would just straight up hump me without any forplay
