I cant offer much in the way of "sensitive" advice.....Im of the belief that if my guy isnt/is doing something I do/dont get anything out of, I tell him...good or bad. I dont see it as being "kind" to let him think he's doing something he's not.
I dont mean to say it in a bitchy way....there are ways to do it nicely....do ya'll watch porn? Maybe you can try having sex while watching a movie, and telling him to try something the people in the movie are doing.
as for my guy....I think he has permanent viagra running thru his blood
he can cum 3 times and still be hard for more. or maybe Im just that arousing to him ha ha ha
