Is my (17m) parents (56f) (53m) relationship hurting my ability to have one of my own?

I am not sure if this belongs here, I am new to this sub but here it goes.

So my parents relationship from my understanding is okayish. Like I am not sure what average or "normal" is but they have their fights, like it varies. Major fights happen every few months or so on average, but miner fights are about a few times a month. It's mostly just yelling, usually at night, but I do occasionally wake up to fitting.My mom has told me she is "about to divorce" my dad for as long as I can remember.

The most intimate or romantic thing i see them do is my dad calls my mom to see tv clips, which causes resistance because my mom, like me, has ADHD and likes to focus on what she's doing. Like i don't know if couples are supposed to be all lovey and showing each other affection and all that or if that's just tv.She has anxiety and OCD like me, (although the former she doesn't know about), I remember her being pretty germophobic as a child, and she quit her job when she had me because she thought if she didn't take care of me something bad would happen to me, not entering the workforce until I was about 13. although once I reached the age of 6 or 7 I could go outside freely without supervision, but I digress.

My dad on the other hand is often the instigator, and brings back wrongdoings regarding parenting from years back (like her letting us sleep in as a young child for me and my brother having to get up on Monday mornings. He isn't an alcoholic per se, but I don't think I have ever seen him limit himself to one drink, and drinks every night til he goes to sleep, and has drunkenly hit me once because I wouldn't give my cell phone over for the night, because he never charged it, and I didn't stay up on it like he suspended. His mother was an alcoholic when my Grandmother on my mothers side let it slip on the phone. It made sense because he didn't talk about her much, and she died a year before I was born so I never knew her.

I feel uncomfortable with intimacy. Like I have only had one relationship that lasted like a week but we realized we weren't right for each other. Like kissing feels weird to me, like maybe it was because my first was so awkward, but I don't really get the appeal of it. Idk maybe there is something wrong with me. Like I like this girl but I feel like if I do I'll beike "what now?" if that makes sense? Like it kinda feels unnatural for me.

Without my parents there are more than enough reasons for my singleness, my anxiety, low self confidence, awkwardness etc. but I want to know what you guys think.

TL:DR: Parents may be in a bad relationship, is this causing my trouble with relationships?
