Sexually transmitted diseases (STD) are very frequent in the whole world. M ales who do not use a condom during their sexual relations are at great ris k. We report cases of STD during six months of observation, among homosexua l/bisexual males who participate in the Project Horizonte. There were 16 ca ses of genital warts, 6 cases of human immunodeficiency virus infection, 24 cages of unspecific urethritis, 28 cases of herpes simplex virus infection , 30 cases of syphilis, 58 cases of gonorrhea and 84 cases of pediculosis. We concluded that a condom must be used in all sexual relations and new cou nseling techniques are needed to avoid this situation.
