Don't worry you'll find others with their bottoms on of both sexes, and a few women with tops on too. There's really no pressure or hassle from anyone so just do as you feel comfortable. As I said in an earlier post, we took young teens, two boys and two girls there a couple of years back, and whilst they wore costumes they didn't feel embarrassed or upset by the nakedness of others. I kept my trunks on first time I went there, my wife just went topless, but on a second holiday we both stripped off and enjoyed getting maximum sun and minimum tan lines. Your choice, it's such a wonderful relaxing place. Enjoy it!
