She has given you a great long list of things you could do that might improve intimacy.
Have you been taking steps to improve all of those?
Have you been asking for sex a lot? because this just adds to pressure. The trick with DB'ing is not to pursue so much. If you are less sexually available she will want you more as it's reverse psychology.
Have you thought of asking her if you can just cuddle for the time being as that's a way of showing her you love her without necessary expecting sex from her.
You said you have sex a few times a month. How many times is that? Once a week in my opinion is normal and if you're putting pressure on her because you want it all the time, this could switch her off (it did me with a fling I had - I ended it because he was asking for sex all the time and I thought he didn't care about me).
If it's a case of differing drives, can you not MB in between times to relieve it or ask her to help you MB?
Is there any 180 you can do in bed that would make her desire it more? Or something that puts her off that you can stop doing?
Was she always lower drive or has she just got lower recently? What types of things did you do in the M before your SL declined?
