I think it's great that both of yall are active on this forum - that's a very good sign. I encourage both of yall to search the archives and read as many threads as you find interesting. There's lots of good information here even if yall decide swinging is not for you.
'Jealousy' may mean different things to different folks. I was concerned about the possibility of hurt feelings when we first started swinging. I discovered that the opposite of jealousy is 'compersion'. Compersion is the feeling of joy when others (spouse in this case) feels joy or pleasure. I think compersion is a positive attribute and jealousy is a negative attribute. Society programs us to accept jealousy as normal and reasonable. When we look for opportunities to experience compersion, jealousy looses its relivance.
