Sensitivity Problems

So, my bf of 6 years has issues with sensitivity. No issues with getting or staying hard but it takes hours for him to finish, if he even finishes at all. I love him and have tried everything i can think of to help but I've gotten to the point that even though my sex drive is high I just don't feel like spending hours having sex multiple times a week. The hours long sex sessions were awesome at the beginning but it just seems like a chore at this point and I hate that feeling. Has anyone else dated someone like this? I would love any advice I can get.
