What are these?

I stayed in a motel last night, these were not here yesterday. It's freaking me out. It doesn't look like bed bug bites. I was also with someone, could it be some early sign of std? I already have psoriasis but that's never caused anything like this.

They are seemingly not raised and don't feel much different from the rest of my skin. They don't hurt or itch. If I need to add more info please let me know.

Also I was an alcoholic for some time but have quit. Mostly, I have a couple here and there but usually abstain.
