DB in love marriage gotta be the worst!

Indian ​M 30 married to Indian ​30F. It was a love marriage, was in a relationship for 2 y​ears before marriage, almost all of it was long distance. Lots of drama at our homes before they agreed. Everything about her is just perfect, love her to the core, but there ​is a catch. Since we were mostly in LDR (met 2-3 times a year on casual dates), we didn't get involved physically (made out just once, thats all) an​d whenever sexual topics came up she used to discuss openly (calling herself very romantic), and also​ used ​to subtly skip it saying "Everything after marriage only" types. I was fine. ​Flash forward, it's been almost 2 years since we got married, and the last time we had sex was 1.5yrs ago. Yes. By now it's DB.

I know she was more inclined towards spirituality, which I didn't mind at all. Most of us are into that yet I assumed it shouldn't affect sexual life of married couples. Boy did I get surprised. We got really intimate in the initial months. My libido is literally off the roof and she's almost Nil (but she was curious in the beginning so I didn't know until later). After 6 months or so, she started saying that we've had enough "fun" and now sex is something that we should do just to produce kids, not like an activity. Like what ?

Now ​I have to beg her every time I wanna get intimate, which I don’t like, so I dont do that anymore. She just never ever initiates, denies like 90% of times when I initiate. Everything else is fine, we kiss and ​cuddle occasionally, love is something that’s holding us together, idk how it works, love without sex, but it has worked enough to not take any solid step. Tried everything, talking about it, expressing my emotions, tried to spice things up, again and ag​ain it’s the same story. For a guy who has super high libido and had pretty colourful sexual experiences previously, this feels like a very hard 100 to 0 hit.

Tried couple​ counselling sessions for few months now but i dont think they're working. She's pretty strong about her spiritual influence and I'm just being told to "adjust". Even I feel it's petty to fight so much about sex and divorce is not even an ​option.​ I am lost, idk what to do, I'm on the edge of cheating, but ig that's super confusing too. I feel like I am stuck forever.
