We are both widowed. We knew each other’s spouses. We both had been married 48+ yrs. We’ve been together for approx. 2 yrs., and sexually active for the past 10 mos. We are having amazing sex together, several times a night. I am a fit 75 and he, despite a mild lung condition, is otherwise fit at 82. It feels and wonderful! This is the best sex I have ever had in my life. But it does seem unusual. Is it?
