Not long ago my husband told me he didn't want to have sex anymore because he couldn't take me rejecting him when I wasn't in the mood. I responded that I would have to think about my next steps, because I wasn't willing to live in a sexless marriage. Luckily for us both, his sex strike only lasted about a day or two. But I get how serious conflicting levels of sexual desire is and how delicate it is to work out! I wish I had some brilliant advice for you. My only thought is still that maybe threesomes would somehow open up the sexual flow? Just a guess. I don't know! Hopefully, your therapist is coming up with some ideas...
