Same here! If I do it myself, I know the pace that I need in the moment and I also have more control on the aim on where my cum is going. Easier when giving her a facial or trying to make it cleaner. My girl does it when I'm cumming on her tits and she just has one speed. It feels GREAT but sometimes she doesn't go fast or hard enough, or does it for too long and I have to beg her to stop. It's just a different situation, and both are good
Good question. To me, whether I finish myself or my partner finishes me depends on what kind of orgasm I want. Finishing myself has a very predictable and intense build and a great climax. Having my partner finish me is like choosing a door on *Let's Make a Deal*. There's mystery. You might get something mind-blowing, or you might get something that's a bit of a dud. But that's just me.
