Afraid that I am denying the truth.

Hello everyone, apologies for the wall of text that follows. A few years ago I saw a sexual dream that had to do with another person of the same gender. This got me really stressed into thinking that for me to see that it means that I am either bisexual or gay. I am a straight male so I never had thoughts like these or even a dream for that matter. Prior to that I found myself when viewing sexual content to be aroused by trans women. I think this was the beginning of the spiral of these thoughts. I would constantly question my sexuality thinking that for me to be aroused by trans women because of the genitalia I am gay or bi. I was constantly seeking reassurance that this is not the case, at nights I couldn't sleep because the stress was so severe. I would constantly look up forums and whatnot to see if people had this issue as well, constantly questioning their sexuality. It got to bad to the point where I would look at men and see if there is any groin response. Thinking that for me to just look at a person of the same gender meant that I want to look at them, that I am attracted to them. I found out that HOCD exists and I found myself that it was what I was going through. I don't like self-diagnosing or jumping to conclusions since I am no professional on this field but after finding out about Pure OCD it made sense and I found it relatable, I managed to get through HOCD after a long time alone by not doing compulsions and accepting things that would make scared, if I even am through it 100%. Now, a few years after I found myself questioning my relationship, stressing over if I truly love my partner, feeling sick that I am lying to her face that my emotions are false. Questioning my attraction towards her to the point where I try to avoid anything sexual because I am stressed, scared that I will not be sexually aroused, even thinking about it makes me stressed. Am I truly attracted to her? I care about her so much but it feels as if I am lying. When things get a bit calmer in my head it feels as if I am just using OCD as an excuse, that I have nothing and I am just lying to make myself feel better. This happened last year and I managed to beat the love part I think but I still struggle with thoughts of attraction, could I be lying to her and I am not really attracted? But why? I closed an appointment with a psychologist in real life and I am stressed that I might get misdiagnosed which would mean that if I do not have OCD all I was fearing would be true. Lying to myself, doubting, repetitively seeking reassurance from different sources etc. Thank you all for reading, I could add a few more things but it is a really long text already and I would really appreciate it if this would be read. Did anyone have a similar experience like this? Am I just denying these things?
