Should I report my coworker for sexual harassment?

So my coworkers and I are always joking around and having fun. I was pretty close with one of my coworkers who has been there for about a month, but recently he’s been acting very weird and making me uncomfortable.

About two weeks ago, he was taking the coffee creamer machine to the back to be cleaned, and some of it spilled on the floor. He saw me sitting down, came up to me, and said, “Oh, you came all over the floor.” I gave a fake, nervous laugh because it felt really rude.

We also have a new coworker, and she and I get along well. He keeps bothering her too. One of my close male coworkers said she looked uncomfortable when he joined a conversation she was having in the back and tried not to talk to him.

Another time, me and that same girl were stocking shelves, and he came over, bent down between us, and got way too close to our faces no personal space at all. We both mean-mugged him.

There was also a time when he purposely drank out of my drink. I said, “I know you didn’t just drink out of my drink,” and he started laughing really hard, saying he didn’t. But another coworker told me he saw him do it too.

One time I was just on my phone at work, and he came into my personal space. I had to tell him, “Bro, can you back up?” Mind you, he’s 29, almost 30, married, and has kids (they live with their mom), while we’re all around 19–20.

Recently, I’ve stopped talking to him as much, and he’s been in a bad mood about it. He even left early last week because I didn’t want to talk to him.
