I used to do this with my ex, it helps they had a slightly larger clit and I have a longer foreskin tip, but it was pretty great! They’d pull their hood back, I’d touch the tip of my glans to their clit head and I’d roll the tip over the clit and jack it, sometimes just as fore play before sex, other times I’d cum on their clit and say I was giving it a warm cum bath, absolutely loved it! Sadly current partner has a way small clit, and aren’t all that sexual, but I at least still have the memories
