Jump out of an aircraft or off a tall building without a parachute and you will probably be killed. Some survive but that doesn’t prove it is safe.
Unless you are both virgins, there is a risk from the previous partner.
Being single the trip to the STI clinic or an online test are inconvenient but part of life.
My biggest worry is dating, not that it happens often and it is unpredictable. Women close to my age 61 are past the change and BB is usually offered, it seem churlish to use a condom and it is so much nicer without. I would feel horribly guilty if I infected one and it would probably spoil a developing relationship, the risks to me, seem inconsequential.
