Additionally instructed never to use gel during sex but always to use condoms. Volunteers will be seen weekly for evaluation of symptoms, laboratory toxicities, genital exam findings (with colposcopy for women, and plasma drug levels. Acceptability will be assessed in focus groups in the month after completing gel use.
