This is a good question. I know you’re asking based on physical sensation alone. But of course the real answer is more complicated than that. It all really boils down to the spark between me and who I’m laying.
That said, if I just went based on which more quickly gets me to the edge of cumming from feeling good, I think vagina gets me edged and ready to blow a load faster than ass does.
Scientifically speaking, I know the vagina releases hormones during sex which intensify the sexual sensation. So that’s probably a little of why I become edged quicker when I’m thrusting in pussy as opposed to when I’m thrusting in ass.
