Bottom here. If I went to the trouble of douching and not eating for a while before sex, then I want it to last a good amount of time. If a quick shooter happens, I'm not mad about it, but I'm not completely satisfied tbh. For me, like half the time I don't cum during sex; I'm just a hole for top's pleasure. So make it last, please.
If the bottom is taking loads with his door open, then a quick shooter would be more efficient since the bottom has more work to do.
