Heart attacks during sex

I have been reading of cases of men who collapsed and died of heart attacks while having sex. In many of these cases, the partners were relatively younger women. I am worried since I am 55 years old with a new and young wife. Does it mean that I will not be having sex again? Kindly help me..

As long as you are in good health with a good Blood Pressure and heart conditions including moderation in sexual activities, you have nothing to worry about. In addition, avoidance of sex enhancing drugs as much as possible will also be of benefit to you.
