  • Experiences of Negotiating Safer Sex with a New Partner (Central Queensland University Australia) - In response to concerns about rising rates of sexually transmitted infections in middle-aged women, we are hoping to conduct short phone interviews with heterosexual Australian women aged 45-64 years who have had sex with a new partner(s) in the past 12 months.
