Grumble said it, Pixies is a great place to share your views and feelings and to ask others their opinions on things. You didn't say, but does your husband suffer from diabetes? Diabetes can definitely affect his ability to have and hold and erection. If that's the case, it doesn't reduce his "desire" for sex, only his ability to perform. Tt really is a good idea for he/you/both to discuss this with a doctor.

Welcome to Pixies. Hopefully you'll find a solution to your problem. Good luck.
