That sounds like real progress to me. The fact that he recognizes the issue and its importance to you is a good thing and a good start.
The toys are actually a very good idea. It can take some of the performance pressure off your husband and still reserve enough of the "good stuff" to share with hubby. For example, he could use a toy to get you close before entering you. You could manually or orally ready him while he gets you ready. By reducing the amount of time he spends banging around, you reduce the potential for upset with his condition.
If he is game, using toys in some form could very well be the compromise that brings you two together.
I suggest you take a couple hundred bucks (if you can budget it) and buy a dozen toys that look interesting. Make sure you get some lube as well. The Maximus lube is the best we have tried. It is water based and lasts a long time. Use the toys until you find the ones that work best for you and just toss the others. My wife has a couple of favorites. Make sure you keep plenty of fresh batteries - for obvious reasons :-)
Don't be embarrassed about using the toys. You are an adult. They are legal and people have been using them for a few thousand years :-)
If you can get hubby to the point of being willing to do whatever it takes to have a fulfilling sex life with you, then I have no doubt that you can come up with a plan that accounts for his condition and your needs.
All the best, -NOPkins-
