We were in the same boat, we both met in high school and had no other experiences until we got in the scene. I remember going to our first couples party. We were so nervous, we sat in the car for like 20 mins deciding if we should go in or not. LOL. We finally got the courage and so glad we did because we actually had a ball. After 5 mins inside we were very comfortable. I should add, we decided we was not going to play with another couple on our first party BUT we met a really nice couple and played that night.
My advice is, JUST HAVE FUN !!! You will have a ball. Make sure you email back and let us know how it went. All the best.
