My wife and I practice "orgasm tease and denial"...I have a lot of precum and that is a good indication to her that I'm getting close to the edge, and it's time for her to call an end to our tease session.
I like to rub his precum in circles on the head if his cock, and all over my lips like lip gloss! Lol
I like it too. It's sexy to make a guy excited and the pre-cum is evidence of that it makes me feel like the guy can't control himself
