Hi Zufriedengestellter Bube (Wildebube?)

I have a feeling that the way forward for your situation is exactly the same as was the way forward for mine - "Just Do It". I had exactly the same complaints of "Pressure" and "Keep that thing away from me" and "All you ever think about is sex" as you are having. What you need to do is remove the pressure that seems unrelenting to the LD and replace it with a nice safe routine where she knows what is going to happen and when - say once a week on a favourite day. Your side of the deal is not to apply any sexual pressure at any other time - flirt and tell her you love her by all means but KEEP THAT THING AWAY FROM HER. On the appointed day she has plenty of time to prepare herself mentally and accept the inevitable and you have the reassurance that you will not face rejection. Make sure that she gets absolutely as much out of it as your imagination can give her so she isn’t left with the impression of being used. Once you are settled in a routine you should find that sex is no longer such a big deal for her and she will allow you to try different positions and hopefully different days. I know it is not exactly spontaneous but three times a month with a willing partner is so much nicer than three times a year after a ferocious battle of wills! Also the anticipation as the magical day approaches is quite delicious.
Persuading her to try Just Do It might not be as difficult as you imagine because she is likely to want a resolution to the problem as much as you do. Tell her that you would be happy to accept once a week on Fridays (let her change to a day of her choice if she suggests one) and in return you promise not to pressurize her at any other time. If she objects tell her that it can be an experiment for three months and if it causes your relationship to deteriorate she can call a stop to it after that. That is how I sold it to my W and after the three months was up she made no mention of stopping because our household is so much happier and peaceful as a result.
