I have to keep cleaning my iPhone screen I can’t stand it to be greasy or have fingerprints on it. Anyone else have this? How do I stop?

I've just started dating this really great girl. She doesn't know about my ocd which is fine but I've noticed that a lot of my intrusive thoughts and worries about not following routines now revolve around losing her or her believing I'm a bad person. I just don't want this relationship to make me so paranoid. I also know have this where if I see a girl on my Instagram or on the Internet, I'll feel an overwhelming urge to clean myself and the device I viewed it on. This is part of a moral reaction and I also worry I'm not being loyal. I feel I should try and not follow through with these compulsions but as they now revolve around keeping my girlfriend I'm not sure. Any advice?

I have constantly been feeling like if I hit one arm, I have to hit the other and if I set something down and it just didn’t look right or feel right I had to do it again or I had to move it to a different spot in my room I’ve had never been a clean freak, which is mainly what I get told is OCD And I don’t know if I should even have this app. I don’t know if I actually have it. I’m constantly worried that I did something in my past that harmed others and that’s why people don’t like me or I’m constantly worried People are constantly watching me and I don’t know if that’s OCD or if I have it so please tell me I will delete this app and never think of it again if I don’t I just really wanna know

Guys I need help. I feel so alone . Basically I have this compulsion where I feel the need to write everything but this stems from me being anxious about EVERYTHING. Like my mom came in my room and I was irritated and snapped, immediately regretted now I keep writing “don’t be mean to mom next time” but I keep thinking about it. Then I think about how I finally left my house today and all the surfaces I touched that could’ve been contaminated and now I’m writing “next time don’t touch this and this”. Then I think about all the things I need to be doing for this week and I’m writing “don’t forget to do this and this” even though I’ve written it 5 times already. This is what happens everyday btw. My brain always thinks about something I need to be doing and making me anxious that I’ll forget it which is why I write it down on my notes app. I’m sooo mentally exhausted I need help pls!! Anyone have any advice ? I used to think I need to stop the writing but really I need to stop the anxious thoughts coming into my head . People say I need to accept the thoughts and let it go but that’s too hard for me
