my boyfriend can go pretty soon after we've already had sex. but, he says im the only girl who he's been able to get aroused with in that short of a period (about 10 minutes, one time it was 5 minutes after he'd cummed) and a few times he's told me he pre-cums and cums way more with me than he ever has. and, the cum feels different in that its a lot more intense and powerful than normal. so, i guess it depends on the guy and the girl he's with.
