I know viagra isn't for everyone.  Some people are not "allowed" to take it but if they have issues, all they could say is, "you know, it's not you, I still enjoy our time together".   "don't worry about it, it happens" etc.  Some may be embarrassed by it but some people don't seem to realise that blue pill can / could / might help instead of looking at escort saying nothing.  I saw a relatively young chap, not obese, fit looking one.   He had this issue.  He seemed kind of grumpy, as if I didn't "help" enough - he didn't give me a positive feedback. Well, he kept phoning me early in the morning and tried to book me to get this problem sorted out.     I think he was wanking over the phone. I blocked him since.   Only if he went to GP.  It could be some medical problems lurking. 

    Thank you.  I will keep that in mind. 

Yes, the last resort.  It always makes me think punters would think that you weren't good enough though in some ways  except those who would politely tell me "it's not you, I have these issues" which is far more pleasant.        Some do attempt the penetrative sex whilst they know damn well (not in an impolite sense) that they DO have problems.  Are they afraid of admitting that this could be ED?   It's like, he has a car. He knows it stopped starting normally, on and off.  It needs sorting out.  He knows.   Clearly, this doesn't apply to the men who are willing to communicate by saying "this doesn't make any difference to the pleasure I get from seeing you".   

Job well done!
