Thanks everyone.

It makes me feel better knowing that I'm not the only one in this boat. I know that a lot of women feel this way, but I figured that women involved in the lifestyle had all gotten over it.
My problems really started when we started playing with another couple our age who doesn't have any kids. Before then, I would worry about rejection, but not obsess about it. For the first time in my life, I started seriously thinking about getting breast implants just to fit in. Breastfeeding for a total of 5 years has really taken it's toll on my girls.
After a long talk with the hubby last night, I think we came up with a solution. We will still continue to play with this couple (they obviously don't mind what I think is wrong with me and we have become good friends), but from now on we will seek other couples who have children. I'm not worried about being rejected once my clothes come off by a woman who has been through the same body changes as me.
Feel free to keep the advice coming though girls!
