My ldr friend with benefits is 34 and I am 53 so is this toxic?

I met him 3 years ago on a vacation in my home state and he lives on the east coast. He is the only man I've met that is a purely kind and a very interesting person. He respects me more than any man I have met in life. We get along great however the age gap will be the deal breaker for any kind of romantic future or anything more than friends with benefits. Should I just distance myself from texting him? If we lived in the same state we would be hooking up. I value his friendship so much. Let me know your take.
