Joplin,
I agree with StacyCat. Slow things down a bit. Try just going on a getting-to-know-you date with the couple before you go any further and slowly graduate to a full swap. Or you might try finding a single male, if your man will go for it, and make it a night thats just for you or at least mostly
. That way you get tons of attention and if your new friend can't perform your husband is there to make sure you have fun. While I'm still somewhat new to the "lifestyle", I suspect these feelings (he had fun, now where's mine?) are quite common. Try to bear in mind that things are not always exactly 50-50 in terms of who gets what on a particular night.
