Hello. I'm sorry to hear this. Honestly, sex isn't everything, but it is nonetheless very important. Physical attraction is our initial attraction. it is not what keeps us together though. Just think about it. At most, your might have sex once a day and that is very unlikely after you have been together a while, A relationship is built on so much more: trust, communication, common interests, etc. A lack of sexual drive can indicate a deficiency in one of these areas though. You are correct in seeing a doctor. Your patience is commendable and to me is an indication that maybe this relationship is worth the extra effort. I hope I have been an encouragement to you. Basically I feel like you are correct in giving it a shot. Let me know if there is anything else I can do to help.
