Mojo upgrade is it worth a try

Not totally dead, but vanilla and extremely boring... Once a month, sometime twice. She comes then goes starfish and waits for the end.

Tried to talk many times about what would help.

Tried for months to be kind and attentioned.. still the same.

3 kids but 12 10 and almost three, none sleeping with us, all sleeping well...

I don't have any ideas on how to turn the tide...

Married 15 years... All is OK except for me dealing with depression on and off.

Anyone in that not so bad situation found a way to improve things? Wondering if she has any repressed fantasies, hence the title but I fear it would do more damage than anything
