Hi there, Wife2Love. I agree with Ashley for the most part, but would like to tack on to her suggestion. Why not consider connecting with another couple via an ad and visiting the club as a 4-some. There is a sense of safety in numbers, and in that way, you would not find yourselves sitting on the sidelines with no one to talk to or interact with. I've never been to a club, but from reading various postings, it seems some of them are rather cliquish.
I would go with the other couple, have a great big huge and welcoming smile on my face, and do all that I could to project pure self-confidence! Strike a balance between being too forward/pushy and being open, friendly, outgoing, and welcoming to everyone.
By virtue of your question, I would be concerned that a solo club visit might turn into a rather demoralizing experience for you at this point. Unfortunately, many people do place great emphasis on physical appearance. However, most of us do, after getting past the first impression, lean more towards finding compatible personalities, those with common views/attitudes, etc. In the long run, there is nothing more pleasant than friends with positive attitudes and winning personalities.
If you read through the other postings, you will see that you are not alone in your concerns of acceptance. While we are not all concerened about weight issues, most of us have our own personal concerns regarding our appearance - surgical scars, age, sagging boobs, (gravity be damned!), etc. It has really helped me to know that many others have the same concerns I have had - I'm not alone.
For me, it's the age thing since I am considered over-the-hill in some circles.
It has caused me to back off from some situations on occasion, but hey!! I figure there is someone (or two) for everyone. Go find that person or two.
Keep us informed of what is going on. And I'm certain that others on this Board will soon chime in with more and better advice. -EBF
