No one makes an entrance quite like Lady Gaga, who appeared on Good Morning America in February 2011 in a condom-inspired outfit to promote safe sex and AIDS awareness. Gaga routinely discusses safe sex with her fans and encourages parents to talk about sex with their children. “I want to get people started at home at a younger age with their children, talking about HIV, talking about AIDS, talking about safe sex,” she said in the GMA interview. “My mother talked to me about sex at a young age, and she always taught me to be self-aware.” Perhaps Gaga’s support will encourage healthier behavior among teens. More than a third of sexually active high schoolers revealed they didn’t use a condom the last time they had sex, according to the U.S. Centers for Disease Control (CDC).
