RE: board short ?
I was just at the beach last week and found I had to wear teeny tiny thong underwear under my board shorts, otherwise the seam was just rubbing me the wrong way, if ya know what I mean! I would have just worn a bikini bottom under there, but I hadn't brought one with me...
Even if the seam thing didn't bother me, they are pretty revealing when you're sitting down in certain positions, and when I was in the water I felt exposed--the water kind of made the board shorts balloon up and float around me. I don't think that was really happening as much as I thought, but it felt strange because it was so much more material than I'm used to having on under water.
