How to gently turn down a 60 year old man from a relationship or should i be with him Pros and Cons ?

I think that there is too much age difference and I think that he should have a lot more to offer you than what he does. And erectile dysfunction sets in about 60 or so, lessening your chances of having a family. There really is no easy way to let him down. Just call him and say that you like him but he is not what you are looking for and then tell him that you're sorry. Sure, he'll be hurt but it will be far easier now to let him go than later when he falls madly in love with you which he is beginning to do.

"I'm sorry but I'm not interested, you should meet people your age".

Simply and concise.

If you want children that bad, they you are wasting your time with a 60 year old man. And I say that because most men want nothing to do with kids after a certain age. So change your age range to 40-45.

The old guy might surprise you. One of the richest men in the US once drove an old car, he may still, I don't know if he still does. He lived in the same house  for about 40 years.A former US Senator fathered children until he was in his 80s and if he has ED, they have medicine that can make him like a young buck again. What I would want to know if I were you is does he have enough money to take care of you and the children he fathers. Does he even want to father anymore, I wouldn't as I wouldn't think I would get to be around to watch them grow into adulthood.

I don't know, the fact you're even considering it means you either have to, or want to, so you know, try on the shoe, see if it fits, if that's what you want to do. If that's the first real interest you've had, it might be a win/win.
