Welcome. Have you discussed this with your partner at all? It's a huge mountain to climb, for sure. But when my wife came to me in much the same circumstance, we were both amazed and the intimacy that grew from trusting each other with our 'deep dark secrets'. That's obviously not something to just jump into without considerable thought, but honesty is always the first step to freedom.
Best of luck!
