I'm 55 and a 24 yr. old guy wants to have with me, but I just can't seem to be able to go there, am I?

why am I so concerned, he will probably satisfy me, my new boyfriend has to rely on toys for me. Or should I just grow up and leave the youth in the past. I don't know. I am happy with my boyfriend but I am disappointed in the bedroom, however I could have a discreet hot encounter with a young guy too, but it would be with allot of guilt, which I can't handle. What should I do.?
