Sex lowers heart attack risk. Having sex on the regular is good for your heart. It is an excellent way to increase heart rate, as well as help keep estrogen and testosterone levels in balance. If you have a low heart rate or your estrogen and testosterone levels are out of whack, you may be at risk for serious health conditions like heart disease or osteoporosis. Research has shown that men who had sex at least twice a week were half as likely to die of heart disease as men who had sex rarely.
