I understand if he suddenly likes the feel of not having hair there but he should be compromising with you. For example, getting waxed. There's no stubble after you wax for a few weeks. If I were you, I'd forego the intimacy for now. If he initiates, I would tell him no and why. If he's okay with you foregoing intimacy and doesn't care to fix this, then I would start to be concerned. I'm sorry you're going through this.
