In my twenties, I was a two pump chump, but I could also recover in 15 minutes, so 3 an hour was nice sometimes.

Now I can last almost the hour, but another pop will normally take two or more hours to pull off.

Of course, is depends on the gal.  Some are very skilled at getting me going again.  And it depends on how well rested I am, etc.

Lots of variables to consider.

The biggest is the condom.  I often opt to come without the condom on a gal's breasts, face, thighs, mouth, or other spot she is into.

Some of my clients enjoy a good 30-45mins of pure pleasure, some get too excited and last only but 3 seconds.

For me, romance is paramount and not the destination.  

Truly, Sex is/can be a very pleasurable experience; an indescribable feeling.

If I control the "pace" I can last pretty much as long as I want to (that doesn't mean I'm one of those guys that "works" the girl until the last five minutes of the session - it means I like a nice build up and release). If the girl is the type that jumps on and tries to make you cum as fast as possible then about 10 - 15 minutes. Those type of girls don't get repeat business from me as it should be as much about the journey as it is about the destination.

All the way until I finish

Never thought about it before, that depends on the lady, some ladies will take you to the edge and back off ramp up again and back off and then get you to the finish line, and oh how good that finish feels when they do that. Other ladies just rock your world until you finish. Both are great, I personally feel that the ladies are really good at reading your mood and which you want, because I've had both happen with the same lady in different sessions. If I'm already frustrated for some reason, I want to get to the finish ASAP, if I'm relaxed I like the lady to draw it out a little. These wonderful women are masters at their art.

Waay too long....

At twenty - a few minutes - and back at it a few minutes later.   I once had a PE (friction on the sheets on the edge of her bed) while doing DATY and by the time she came a few minutes later, I was ready for the main event and blasted off 10 minutes later..... and was ready again 5 minutes after that.   By mid thirties - a good solid half hour with a lot of concentration.  Easily do two or three in a session.  By mid forties - any amount of time I cared to put into it - but it took some concentration to hold off - just a matter of how long my legs and hips could hold out.  Two was pushing it.  At fifty - I have to actually concentrate on having an orgasm or it ain't gonna happen.  I HAVE to do multiple hour appointments.

I would have killed for the endurance I now have when I was younger.  I could have done a half hour appointment back then....  I really did not appreciate what I had.  Watch out for what you wish for...

lately,, About an hour and one half....

Then I wake up and go pee. But p4p I went almost that long because of her skills.

If not, about 10 minutes.  If I use some tri-mix injection though, that bad boy is going to stay up for 2-3 hours, regardless of orgasms and take as much punishment as I can give him.  That stuff is magic from a male's point of view, but must be a provider's nightmare.  

I can see why tri-mix or quad-mix is the party drug of choice at sex clubs.
