whats the normal amount of times a guy can cum? if you cummed three times(girl)?
...as many times as he is willing, I imagine.
But he's bound to get sore and dehydrated at some point in that 3 hours...
It also depends on the guy... Are you referring to orgasms or when a guy actually ejaculates?
There is no 'normal' same with girls, it completely varies from person-to-person.
depends on when was the last time he had sex before this time..
...in how much time?
