My aunt, born in 1922, came down with Polio when she was three years old. She spent her life on crutches and back then, because how Polio was contracted was unknown, not many parents allowed their children to play with her. So, my aunt lead a somewhat sheltered and isolated life. She wore a leg brace and used crutches. Back then, there were no handicap rules and regulations for ramps in public places, like in today's world where every public place must be handicapped accessible.
As a result of the time she was raised and the stigma against Polio, she never dated. Because she never dated, she never kissed a boy/man.
She survived to the age of 93 without a kiss. So, I would say that if she could go through NINE DECADES without a kiss, it is entirely possible for anyone else to do so. Including me.
