People in Open Marriages Only Please

So I need some help. My husband and I have polar opposite sex drives. Mine is insanely high, and he's contemplating whether or not he's asexual with how little he wants sex. While I wait for him to want to have sex again, I don't get intimacy much, and he won't do alternatives. He doesn't like to perform oral on me. In the six years we've been together I've received oral like once a year, twice if I'm lucky. I've expressed that I truly enjoy oral and it's still not something he's willing to do. I understand that and I won't force him to do so either. So, not only am I not getting much sex, I'm also not getting anything to tide me over. I'm tired of seeing us struggle and suffer because no matter what we do, one of us is sacrificing comfort. A vibrator doesn't do much but make miss the feel of my husband more than I did before. If anything, it's now more like a sleeping pill, helps me sleep.

My husband and I are going to try one last thing. If this doesn't work, I'm right back to asking for an open marriage. I've tried approaching the subject with love and understanding and letting him know that I feel if we structured it the right way it could be beneficial. I don't even want to have sex with other people, just stuff to tide me over until he's ready to have sex again. If he set rules, I'd be more than happy to follow them. One of his points was that it would be weird when we have holidays. "Hey kids, merry Christmas. You have gifts from mommy, daddy, and mommy's special friend." I explained to him that I don't want that kind of relationship with a third party. It wouldn't be for anything more than sexual activity and that I wouldn't let them into my home life. He also seems to think that I would fall in love with whoever it is. I explained to him that I can't trust people that way enough to form that kind of relationship with them. He says he doesn't know how I can love him but want to share my body with anyone else. I explained that just because I'm asking to be sexually satisfied and that our current arrangements don't work doesn't mean I don't love him and that I can separate sex from love if it isn't with him. I'm having a difficult time expressing how I feel in a way that he might understand, and a lot of his opinions on the matter can be addressed by making rules and boundaries that I can easily and readily follow. My sex drive wasn't anything I hid from him. He however hid his until after we were engaged. Thank you for taking the time to read this. If you have advice, please share. If you don't have anything nice to say, don't say it at all. If we hadn't practically exhausted all other options I wouldn't be at this point.

Edit:

I'd like to be clear that I don't see a lack of sex as a reason to end a marriage. There's a few reasons like cheating, abuse of any form, and lying that I would leave for. I feel as though when you love someone you accept all parts of them and both work toward a solution. I also feel everything else can be worked through. Thank you for the advice given. I'm going to have a conversation with him regarding therapy. If anyone else has advice I'm happy to hear it as long as it isn't leave him. That isn't an option because I love him and he hasn't abused me or cheated on me. He's an overall great man. Also, we didn't know he could be asexual until after we were married. He just kept slowing down on sex after we got engaged. I feel I should have said that earlier.
