It depends on what you're trying to do. Are you trying to have an orgasm but you can't? If that's the case, you should see a doctor to find out why. You might have a medical condition that is making it difficult to climax.
But some men enjoy "edging", which is sexual stimulation for many hours while holding back from having an orgasm that they could easily have. They just like to stay in that pleasurable state for a long time before finally letting themselves climax. This is not dangerous.

Depends On How Long YOU can do it for... As Long As You And Your Partner Are Rearing To Go.Not sure about 'without a break' but if you Do experience and have a little practice, you'll have the time it takes you to feel satisfied.In most cases it takes the Guy to fulfill the needs of his partner.For us(guys), it is easier to get to climax but is more important(speaking of myself) to feel your partner satisfied from having a sexual act,not just being in awaits of when you 'sneeze'.Half an hour,and hour,2,3,5..Whatever it takes you both to get DONE.The time itself isn't the key-factor.What really matters is your own sense and the emotional background during sex.
Have sex
It helps if there is a lot of foreplay before sex. This makes it easier and faster for you to reach your peak or climax. This will be different for you and your partner, but usually my boyfriend and I have about an hour of foreplay before sex. This helps make our peak higher and more pleasurable. Also try to "set" the environment to a romantic setting.
I would think coming together in sex means.. both parties reach their climax at the same time or orgasm.
