Okay not really a "slutty" confession yet but Im starting to picture where this situation might be headed. I'm horrible at managing my thoughts so I'm going to try to make this as organized as I can lmao

I (24F) work at a beverage production plant. I also work with my boyfriend (31M) at the same facility in different departments. Sometime earlier in the year this guy was hired for sanitizing the machines. I'd see him around but never spoke to him. Soon we eventually start chatting with each other. He's (35M) very friendly and talkative and playful with me.

It was small stuff, things like standing really close to me when talking, prolonged eye contact, and messing with me playfully when he'd walk past the window to my lab.

Somedays I've noticed him follow me to breaks as he would see me go one way while he was walking the other way and then turn and follow where I am going instead.

We are pretty good work friends I'd say. We vape together and he will often playfully poke or grab at my arm or my back. On one occasion he started massaging my upper back while I was sitting in the lab. He also would make sexual jokes with me frequently.

Fast forward to a few days ago. He first comes into the lab and I'm busy with my back turned. He comes up behind me and to get my attention, he places his hand on my lower side/hip for a moment or two. This was odd because he could have tapped my shoulder or said my name to get my attention but instead did that. I'm feeling bad about it but I kind of got a little hot when he touched me there.

Later that same day he comes back into the lab while I'm sitting browsing my phone. He then goes "ARE YOU WATCHING PORN??" before coming up to me. I tell him something like "duh, I'm brushing up on my kamasutra" but say it jokingly. He laughs and we go back and forth a little bit talking. There's a small pause in our conversation before he suddenly tells me "you can practice with me".

He leaves and comes back again a little while later asking me "what are you doing? You're supposed to be practicing your kamasutra, come on let's go practice together. We can go in the elevator"

I'm floored at this point and my brain is racing. I hesitantly start to follow him towards the elevator. He's honestly very handsome and I do find him really attractive. We stand in the elevator but neither of us make a move. We just ended up hotboxing the elevator instead haha.

At this point I'm almost 100% sure he's trying to get in my pants but I don't know what to do.

The biggest problems is that I'm in a very healthy relationship with my boyfriend who works at the same job as me and my coworker. I'm just... a horrible person.

Another very important piece of context is that he's married and has young children and lives in the same household as all of then.

I'm tempted to test the waters more after our last interaction
