It sounds like slow and steady will win the race for you, so keep going in the direction that you are. If she is open to watching porn with you, select some MFM threesome movies. That may raise her interest some. Before we started in the lifestyle, we also were back and forth on the moral aspect of it. We finally came to the consensus that as long as we agreed on it and only did it together, it wasn't really cheating. Others may disagree, but we all justify this lifestyle in our own ways in order to enjoy it. Keep the dialogue open with her without being too pushy and the two of you may just be able to enjoy what we call Sport Fucking too! Good luck to you both. 😉
