Not only recently, but for our entire marriage, every time I have ever tried talking to her about sex she gets extremely defensive and not much comes of it. I once gave her the book Hot Monogamy with a card in which I wrote how I felt but she basically just blew it off and never even opened the book.
Regarding trying different things, as I said, she barely lets me touch her. It’s basically just in and out.
I have read SSM, but it’s been a while and perhaps I should re-read it. I’ll try The Playbook.
