Can this condition be treated?

I always considered myself straight. I like and orgasm to girl's pictures and videos but I am a virgin till now(26,M) due to religious reasons.

I was talking to a girl for marriage for around 2 months and I did not feel any sexual pleasure or attraction(met her once) other than that chat and voice calls. The only sensation I had was happiness and care for her and longing to talk to her

Recently I thought more and realized even while masturbating, I get a lot of pleasure in my penis but there's nothing in my brain, no pleasure. In between masturbation, I closed my eyes and felt nothing in my brain at all, probably only stress(life is stressful along with these new doubts)

I want to feel the sexual tension in my head. Not sure if these are issues related to asexuality or if I am straight but don't have dopamine released in my brain which can be somehow fixed
