I think he is tired of the constant disappointment of not being able to perform the way he wants to makes him not want to have sex but like I said at the beginning of my first answer it's hard when you have been together so long to keep things exciting and new and if both aren't making an effort to make things better. I don't think the two of you are ready for a sex therapist yet I think you should start out with Couples counseling first and figure out when and why you got to this place and then once you can figure that out and what you both can to do to make that better then you could try a sex therapist. If you do not get the help you need now it may be the end of your relationship because neither of you are happy and it's not getting any better doing it alone.
Counseling can be quite affective if both people want their life to be happier than it has been but you both have to be completely honest about the way you are feeling and what got you to this point. This means totally opening yourself up to the fact that you have an issue and then be able to do the work to correct those issues together. Also you have to give it some time and not give up, these problems didn't happen overnight and they are not going to fix themselves overnight neither.
