How should I handle this?
The short answer: communication, respect, honesty.
Talk to her about the experiences you had, how they made you feel and what you hope for. At the same time, respect her limits and don't push. If you try to get her to move more quickly than she is willing, or do things she isn't comfortable with, it will not end well. So, listen to her as well... find out what she thought and felt about these experiences. Encourage her to be honest. Reassure her in a truthful way.
A successful swinging couple needs to have a strong relationship. A key for my wife and I is the unwavering knowledge that no matter who we have sex with and how much we might enjoy that sex, we're always going home to each other at the end of the night. She is the woman I want to spend my life with. Simple, and as complicated, as that.
