text: 1 out of 6 have std's? i heard that 1 out of 6 non-married, sexual active women have an std or have had an std. can this be correct? it's not just females. more than half of all people (male and female) will have an std at some point in their lifetime. each year, one in four teens (m and f) contracts an std. one in two sexually active persons will contact an std by age 25. women are more susceptible to stds than men, and 60% of females dont know that. all i can say is get tested for stds if you or your partner have had other partners.
