There were a couple things we did save for after the wedding--for the honeymoon. I have to say it made them a very special and valued addition to our sexual relationship. Even now, when we do them it is for more special occasions, sentimental times....
On my part, I performed a pretty hot striptease and fully, 100% naked sex. I was always so ashamed and embarrassed over my stretchmarks and belly pooch that I always made sure my tummy was covered in some manner.
On his part, he saved experimenting with prostrate play. It did not work out for him, but we have since figured out other small but related things he does enjoy.
Then there is the BIG change in our sexual relationship about 8 years after we were married and found sex toys, porn and other fun means of exploring our sexuality...neither one of us had ever experienced many of the more risque' or non-typical activities we tried and currently enjoy together before--and we are still discovering new ways to please and enjoy each other!!
