Hi attached lady,
I have the same problem of premature ejaculation. The cause of my problem is the lack of sexual intercourse. If I only get to do with my wife once a week to ten days, I come really fast, 1 to 2 mins. If I get to screw her twice in 3 days, i last about 30 mins.
For a more scientific response, see

Don't hurt his pride directly or indirectly. That will only aggravate his & both of your problem.
Best wishes.
