I'm worried about belonging here

As a teen I came out as bisexual, because I feel attraction to both genders, however with time I realized that might mean esthetic attraction instead of sexual. I never liked how genitals looked, I never felt the need to have sex, or even kiss someone. I thought it was just me being a late bloomer or something.

I got into relationships, mostly online, but to me having a partner meant having a very close friend, I liked spending time with them, play videogames, talk about life, but when it came to flirting or kissing it felt like my brain froze time and asked "do you actually want to do this?" And the answer was no. And even though I explained my needs, expectations and boundaries we always broke up because I just wasn't interested in romantic or sexual stuff.

I sometimes fantasize about kissing or touching someone, mostly fictional chatacters, however it's rare and it's definitely not something I want to do in real life, whenever the actual opportunity rises I'm instantly repelled, it's just not something I want to take part of in reality

Now here's the problem: I had been having health problems that seemed to be non-related, but after some years of searching I found out last year I have hormonal imbalances, mainly hyperthyroidism but also other hormones are a bit high (prolactine), a symptom of this is also lack of libido, so I started wondering if maybe it's been that all alone, and in normal circumstances I would've just treated these issues and find out, however withing half a year we also found out I was resistant to treatment, and two months ago an MRI concluded the cause was a pituitary tumor. The doctors say it explains my symptoms, the heavy hormonal imbalances, the chronic pain, mood swings, hypersomnia, everything, including lack of sexual desire and interest in deeper relationships.

There's no solution yet, since the doctors have decided surgery is risky but haven't offered any other options yet. So I will continue to be like this for a while more.

And I constantly wonder if I have the right to be a part of the community, since my lack of interest in romantic/sexual interaction might be caused by the tumor.
