Well, ok---there are " secret sex " spots on all the ships--you have to go to the pursers desk ( preferably late when no one is around, ) ask them for the " special " glasses you have to wear in order to find the secret sex spots.
The glasses are similar to 3-d glasses and the secret spots are marked with smal X's in a certain color paint that can only be seen after dark by wearing these special glasses.
There now--the secret is out and everyone knows, it's not a secret anymore ---dang it !!!
