Is this question really about what you should wear or about tan line definition?
In a public shower situation a speedo tanline may gain you admiration and toleration, a very brief bikini tanline will make other guys wonder what you have been up to, a thong tanline will make the straight guys worried and the gay guys step closer and an all over tan makes guys have to decide whether you were born that colour or have been naked out in the sun.
Some people always wear a watch while sunbathing on holiday to create a reference sample for their friends when they come back.
In the days when schools had compulsory showers after PE and games the children of naturists would become nervous of going naked, not because they minded being seen naked on the beach or at a club, but because they might get obvious all over tans when they got back to school and were seen in the showers.
In the privacy of your own enclosure wear whatever you feel happy and confident in, but test out a least one swim thong for that feeling of the front being tightly held while the water flows sensuously over your buttocks.
Wearing different suits each day may mess up your tan lines but will certainly add a little excitement and arousal to your sessions.
