Hi, I'm a 30y male and I'm in a relationship for the last 3 and half years. She's 28 and bi.

In the first year of our relationship we decided to sleep with another woman together. It was a great experience for both of us, It was her only Second time (having sex) with another woman and the first threeway for both of us. She was even considering become a true cuckquean.

As we were in the start do our relationship, It was fun and all. But as we were getting more serious, she started to be more afraid of doing again due to jealousy, so, I stop talking about it so I wont hurt her feelings

But I trully miss that and wanted to try again, Just don't know How to bring this subject back. Any suggestion on this?

One important point is that she is very insecure with her body and have low self steem. I try to make her feel better everyday by doing positive comments about her qualitis, looks, and all.

Any help on showing that this is only physical and sexual, there is no way that I would stop loving or desiring her?
