I have read many of the posts on this forum and have remembered many experiences. However there is something younger women here need to know. An older man may not have the stamina a younger man has but we are very , very experienced and overly enthusiastic when it comes to a woman's pleasure. Something I heard when I was a young man was " if the penis fails you always have a tongue that works.
I am in my later years but still functional. But I more or less prefer giving oral sex to the ladies I encounter no matter what the age ( as long as they are legal ) No complaints so far. But younger men take heed. Ladies really like that teknique.
