<human>: My fiance and I started dating when we were about 18. We lost our virginity to each other, and never had any sexual experiences with anyone else. We have openly talked about how we are both curious about having experiences with other people, and decided to have an open relationship so we can have the experiences that we feel like we are missing out on.

Now, I didn't want to just jump in head first, and we both agreed to start small. With like, sexting, sending pictures and stuff like that. To make sure we're both comfortable before we come home and say we just got done having sex with someone else.

I met this guy online that I've been talking to. Well call him Jacob. He's pretty nice, I haven't seen a good bright picture of him really but we've talked for a little while. I was super turned on the other night while talking to him and my fiance was on the computer playing a competitive game. So I had phone sex with Jacob, and got off while talking to him. It was a lot of fun, I actually really enjoyed it and got into it.

When I woke up the next morning I felt horribly guilty. Like I cheated on my fiance. I still felt awful today. This morning I talked to my fiance and told him what happened, and how I felt. He only asked if it was while he was in bed with me because he would have been annoyed if he was but I told him of course I wouldn't do that. He reassured me he wasn't mad, was glad I had a good time. He kept laughing at how bad I felt and telling me it was okay. 

My fiance suggested that I post how I was feeling here to see if anyone could give some insight. I really enjoyed it in the moment and I want my fiance to be able to feel how good I did too. It's fun, and nice to know you're wanted by other people. And I know this is just a deeply rooted feeling I need to overcome.

Provide a brief overview of the text.
