It's not surprising that the over 50 or 60 group doesn't practice safe sex. In my 20s and 30s if a man tried to use that line about "I just can't feel anything with a condom on," I'd laugh because after all, men in that age group get erections at the drop of a bra strap.
Fast forward 20 or 30 years, and I have more empathy with that statement. The good news is that men in that age group often have regular doctor visits and so can request blood tests if a woman stands her ground.
OTOH, rampant sex in the old retirement home makes my brain hurt. Truly.
