Dave - Oh man, I like your list. Althought I do not have the LD spouse issue, I can sympothise with some items like try new and improved items, frequency etc. I would suggest buying a small token that may help. This Valentines day I bought a small silk pouch full of scratch off cards called: "52 weeks of naughty nights" at pureromance.com (I bought other things as well - this was for "us"). There is also a 52 weeks of ...Romance which I just found tonight.
These cards are divided equally for him and her - We are on week 2. The first week - Her, the card read something along the lines of leave a sexy note everyday for H telling him to be ready for the weekend, each day increase the "sexiness if you will", by weeks end, he will be ready to explode. I was getting little love notes in my lunch everyday - I could hardly wait to open lunch and find it. This week is mine - the card read to offer myself to W as a sex slave and do whatever she desires on 1 nite - This has not happened yet but I can see her leading up to it - the anticipation is killing me If you asking - we were not like this before, we were not bad but not this exploratory if you will. I know thi sis not a complete answer for you or me but I think it is a great start which will lead to non-prompted LM sessions...
Another post that I loved here at the BB (It was Cemar's) had a link to the following site. This was for woman who are having trouble getting the H's attention. I would have to say if any woman followed this, her H would be Wow'd also. Link for woman to follow to get H's attention just my .02 MNDad
