These FMLs are so annoying. Look, your "problem" is that the guy is too attracted to you, and came right away. Here are some things you can do about it:
1. Make him come once first, then have sex with you. See how that goes.
2. Do a lot more foreplay. If you're that concerned about not getting enough action, have him eat you out first or finger you or use a vibrator on you. If you've already come, then it's not even that bad if he can't last.
3. Act like he's some sort of failure and your life is some sort of a disaster.
Sex is always about working things out. Stop whining just because it wasn't earth-shaking right away.
