If you feel you want more after, why not just have another round? I have never really considered this much, I would never look down upon a man for lasting too long or going to fast. If I don't feel that I have had enough attention I will be sure to point it out. Sometimes sex seems to last longer than others, that is great. Other times while knowing that it has been a while and an early release is likely it is just a good time to make sure there are more efforts towards foreplay to make it a more fulfilling experience.
Another thought is it can take some trial and effort to make changes during sex that slow or remove direct stimulation on the penis to avoid releasing too soon, stopping and restarting periodically to increase the duration. You can try the squeeze method as well. This involves either the man or his partner squeezing (fairly firmly) the end or the tip of the penis for 10 to 20 seconds when ejaculation is imminent, withholding stimulation for about 30 seconds and then continuing stimulation. This can be repeated until ejaculation is desired. Of course the stop and start method can be used with the squeeze method as well.
The bottom line, is do what it takes so you both have fun.
