Wife seems uninterested in intimacy — not sure how to move forward M29 F29

My wife and I have been married for six months, and I’ve been struggling with our intimacy. She rarely initiates, and when we do have sex it’s almost always the same position she’s comfortable with. There’s little to no foreplay, no effort to dress up or make it feel special, it usually just happens with her in pajamas.When I initiate, about 80% of the time she says she’s not in the mood. When she does agree, it often feels like she’s doing it out of obligation rather than desire, which makes it hard for me to enjoy it.

What confuses me is that she does enjoy using a vibrator (something I actually suggested to try to spice things up), and she’ll use it to orgasm multiple times. So it’s not like she has no interest in sexual pleasure, just not much interest in engaging with me.

We’ve talked about it a few times. She understands how it affects me in the moment and seems sympathetic, but nothing really changes long term. After a while things just go back to the same pattern.

I love her and don’t want this to turn into resentment, but I’m starting to feel unwanted and unsure what else I can do. Has anyone dealt with something similar? How did you handle it?
