US cit. marrying a Brit cit. in the states. We don't want to change cit. ship. Love to travel the world.?

We are in the UK now and have been living together for 18 months. I am on a visitors visa and do not work here. We plan on marrying in the states in Aug. of this year. Stay in the states for a few years after that and then continue traveling. We don't want to give up our respective cit. ships. Just be together and work on either side of the "pond". What is the best way to do this? Thank you in advance. Kimera
