I see you have just joined Answerbank. Not sure what you are asking here. A man is usually after what he is usually after... You have told him that you have herpes and he is not bothered. The fact that he has grown children and is 60 is irrelevant.
erm if he is 60 then he has a 60% chance of having herpes antibodies himself - oral HSV but I think they cross-react....
frankly I am amzed its not more.
and also while I am at it - I am astounded that with all the sunny weather we are not deluged with 'Herpes epidemic outbreak shock' articles in the newspapers
Like Ummmm says, it sounds like he really likes you. The question is do you like him? If not, then you need to tell him that you don't feel you have a future together
