Answer:
The blood is use to flowing to and from the heart and your brain, this keeps the veins flowing naturally, and smooth.
The answer is pretty simple. Sexual activity is very strenuous. It's an aerobic workout. If you are out of shape and begin to tire, the natural end to it is orgasm. Then you get to rest. So, if your aerobic capacity is up from regular workouts your body can naturally sustain the activity longer.
Keep it up and have fun. (No pun intended)
