My boyfriend and I are in an LDR and did one of the most fun things we have ever done in the bedroom. We went through all the positions on this site and made a list of the ones we hadn't done and even some that we have. We then set a timer to go off every 2 minutes and devoted ONLY two minutes to each position, no matter how good it felt. It was a lot of fun and even made us appreciate each other more, because some of the positions (Amazon, especially) reversed the roles. It was an amazing night. We had a lot of laughs, and the torture of the time restraint was awesome.
If any of you do this too, let me know how it is for you!
