No, you made that boundary for a reason, if you break it it will go bad. Remember her reasoning. I am a Cuckqueen, always loved the idea in the early days of crossing the boundary, but I knew this. Me and my husband spoke in length and I promised him it would have no issues with us, as a couple, as a loving couple and with our sex life. I love the fact my husband flirts with other woman, I love the fact he can have another woman as I totally get turned on by this concept as well as the reality of the whole situation.
If I had made boundaries, I know, as a woman, in my head, crossing that would lead to complications. After all these years with my husband, and I am now 52, I still love the fact my husband flirts, and plays (if a lady he fancies comes our way), although we are looking for the right woman for a long term, friendship with benefits.
I wish you well, but please, if you cross it, cross it mutually, and talk openly, without alcohol and after you both have made love, so there will be no sexual tension. xx all the best xx
