The path swinging doesn't have to follow a script. If you love her, let her start playing ahead of you. Ask her how she would like to play with other men, discuss it, then to show her how much you love her by letting her without immediate expectations of reciprocity. That's essentially what my husband did for me and I loved him all the more for it.
It took several years, but I overcame my jealousy in an ephiphany one day and now he plays too, and it is a real turn-on for me. As a bonus his current gf has become my play partner as well, introducing us to a wonderful world I hadn't considered before.
All this happened because hubby was unselfish when I would never had moved ahead.
