I’m 84 and take an erection drug—Cialis. I enjoy a lot of sex. According to my cardiology tests (I’ve had stents and a valve replacement) I’m supposedly 52. I’m in the gym doing high intensity internal and weight training 5 times a week. No problem. I think sex is great. As you say, it doesn’t have to involve intercourse. However, all that said, I’m wondering if the meds can be harmful over years of use. Cialis work amazingly well for me. But I wonder about the long-term effects.
