3-5 minutes, an hour, it's all subject to interpretation. Maybe the hour long f*ck session, the guy is into the duration of it, he just likes to f*ck for hours on end ? The 3-5 minute man, he might simply be so into the pleasure that you take him 0-100-0 in that brief a time. If both got the job done, the equipment works obviously, but it's just a matter of what the guy's personal agenda/goal is.

Other explanations, the hour long guy may be more considerate, staying harder for longer for you to get off. That's a double edged sword, it can also last too long for some women. Then he might just be scared, that if he doesn't give you an hour of pleasure, you may go elsewhere for the other 55-57 minutes of f*cking ?

The 3-5 minute man, his interpretation might be that you want results quickly because your definition of satisfaction is knowing you can get him off in an instant ? Maybe he figures the foreplay should've been enough & that it's time to climax in that regard

Hard to say without simply just asking either guy ? Sorry to be so vague with this response.
