False start or slow going?

My wife and have been together for five years or so. Before we were married we had a pretty open relationship, she didn’t have a problem having sex with other people. Those other people always worked out to be my friends, other than one instance where she met a stranger, and that is fine by me. After getting married she still expresses interest in cuckolding me and has, on the very rare occasion, brought a work friend of mine home for dinner and sex. We have talked about why things have slowed down and her answer is that she has no desire to go out and be a hotwife in public. This is problematic as it is difficult to get to our house for most people.

I understand my wife’s reluctance to dressing the part and meeting new people as we have both put on marriage weight and she expresses his displeasure with her current appearance. As much as I try to support her and reinforce her, she just doesn’t feel the part (I assume). She is also very shy recently and concerned about my feelings. I will remind her that this is something that I want to experience with her and that I have always been comfortable exploring together.

As far as our sex life goes I am able to satisfy her adequately and she is fine just being with me. My friends that she has been with were hit and miss, while all of them were better fit than me and equally or better endowed, only a few would satisfy her (The one she still sees can leave her a satisfied mess).

My question to the community is am I at a point where this just isn’t working out? Have I missed something or am I at a point where I should just leave it alone?
