Followup since you asked for a mans answer here you go. It last as long as necessary. It'll last until the bed breaks, it last until she's totally satisfied. It'll last until she's lying on the bed with her perm sweated out, totally exhausted, snoring from multiple orgasms. Nothing less will do!
Where's the remote?
Your saying "1 hour max" what if he has a different schedule? What if his schedule leaves you unsatisfied? Then you would be complaining. What if your "1 hour max" leaves him unsatisfied?
You can't put a time meter on great sex. Because when the sex is great you will (or should) feed off the other person's sexual energy. When that's happening time flies by because nothing else but satisfying your parner should matter.
BTW We
WILL try again later!
