I (25M) and my girlfriend (25F) are together for 7 years, open for a year and a half. We are currently long-distance.

So far, she only actually slept with one guy, almost a year ago. She went to some dates earlier this year, but didn't like anyone. And she suggested that she wasn't also planning to date anyone in the next stint we spend apart. (We are currently together with her summer vacation).

In my part, I have slept with 6 or 7 people. And played with BDSM with all of them.

We share a lot of information with each other. I explicitly asked her whether she wanted to end the open relationship, since she wasn't using it on her side, but she said "no, it's fine".

She doesn't like degradation.

I like the current status quo, but 1) I fantasize one-sided open relationships a bit, in the cuckquean fantasy and 2) I think I'd sleep a bit better knowing there's no chance for our relationship on her side.

(I'm not jealous. At least not more than a healthy amount of jealousy. My biggest worry is always our relationship breaking apart long term. So does she)

Should I suggest her to close on her side?
