I've always, even when I was younger, been only able to have sex once a day, maybe twice if it's spaced out by 5 or 6 hours. Yet, I hear about people doing it 4 or 5 times in one day.
Some guys come too quickly. I've always had the opposite problem. I take too long. So, I have to wait 2 days to be horny enough so that I can finish at a normal time.
What's a normal frequency for a married man at my age?
