You need to find another love language. Physical intimacy doesn't need to include PIV. If your love language is PIV, you're gonna have problems. Guess what, if she gives birth, or gets sick, or gets old, or whatever, she's gonna also stop being able to have sex. Tying your self esteem to how much someone wants to fuck you is toxic and you're creating your own misery here.

You're right, you don't get to pressure her into what she doesn't want. Her body, her rules, and if you pout and guilt trip and fight and cry about it, you're basically emotionally manipulating her into using her body for your sexual pleasure because you're threatening to self implode otherwise. That's also manipulative and toxic.

Get a therapist. Breakup is optional but you MUST work on your mindset of tying sex to your ego. You might be sexually incompatible but even someone that's on the same page as you will still have dry spells and your libido is still no one's responsibility but your own.
