Make sure its with someone that you like to do some of the same things other than sex. I use to have a cabin before the boat. One provider I took to the Adirondacks was a disaster almost. We got along ok, and like each other. But there was very little that we both liked to do. There is only so many things to do up there. I would think the same on a ship. And you would want to do some things together.
And you would not want to try to many things that would be new for one of the two. It was to be my first time for sex outdoors. It was her first time to take a air cab from one lake to another with a canoe strapped to the small seaplane. We did the outside thing the next day after she felt better LOL.
As I help her out of the plane. Please not on his plane or my
canoe, to late. Well at least it was not his plane. Ever try to keep a sick girl from falling in a lake. As you are standing on a pontoon.
