Good idea or not?

The romance and passion seems to have withered in my marriage. We absolutely love each other, but sex is perfunctory or, more alarmingly, seems like a comedy routine where I am the punchline. There is no sweetness in any of it and no intensity or passion either.

Since actually having a conversation about this only seems to cause my husband to throw up his defenses, which then causes me to apologize, take back everything I said, and declare that romance lives and our sex life is amazing, I am considering putting everything down in an email or letter. I am much more articulate in writing and this would give me a chance to say what I want to say without being interrupted.

I know there are things I need to work on. For whatever reason, I am horrendously ticklish anymore and have a hard time not pulling away when touched. But what I would like is for my husband to work through it with me, instead of going on about everything we used to do and how he can't touch me at all anymore. That is not true and I have tried to tell him what I need in terms of stimulation, but he takes it as an insult every time.

Should I write it all down and give it to him? I want to feel like I am worth the effort. Right now I just feel like an irritation.
