I think I might be ocd

I need to talk to a therapist on this but I'm sure we all know how they dislike when someone has an idea of what's going on inside their mind. Maybe it's to prevent misdiagnosises.
I as a teenager showered once in the morning and once at night and I brush my teeth until im sick and then i do it again.
I didn't do anything "dirty" afterwards back then. No bathroom. No burps. No gas. No food after I brush.

I have asked partners to shower and have washed them myself to make sure they were sterile. I randomly boil dishes, and I wash my hands twice sometimes.
I refuse to sit on most toilets. I have washed someone's toilet when staying with them.
I get sick from food I didn't prepare and refuse to eat at most parties.
I got mad at my dad as a kid for spelling incorrectly on his grocery lists.
I wanted antibacterial wipes as a kid. Really bad.
I bleached my shoes a few times for no reason.

Even when I know I have put something away correctly I check again a few times. If I close a lid and I'm pretty sure it's on right, I do it again two times.
I obsessively make sure when I drive the mph gauge is perfectly the speed limit on the dot.
My own body hair has to be shaven perfectly or I'm upset.
I don't like eating or drinking after anyone ever. At all.
I make sure to do the same routine every single day and if someone invites me out during this routine I decline.
I refuse to sleep during the day.
If I have a cut, scrape, burn, scratch I make sure to dress it morning and night strictly in my routine with peroxide, antibacterial, and a bandaid.
I have to floss, then mouthwash, then brush. Strictly that order.
Is this ocd?

Hello and welcome.

I mean, beyond being a germophobe, are these compulsions to allay some fear? Such as checking a light switch over and over, for fear of a fire starting, that sort of thing. We have obsessive fears, which drive us to do compulsions...
