Re: How Soon?
It depends. All guys experience something called a refractory period, where they physically can't get an erection after coming. However, it varies tremendously from person to person. Some guys can get an erection again almost immediately, others need much, much longer. If you still want more sex after he comes, you can always play with toys together, receive or exchange oral (even if he's not erect, it still feels good :-)), etc.
