Unsafe Sex in the City

20-year-old gay porn star Lloyd has a double dose of bad news from the clinic, 31-year-old Heidi is terrified that a bout of chlamydia as a teenager has left her infertile, and housemates Martin and Marissa can't agree who should carry the can for an outbreak of scabies.

John comes into the clinic hoping he won't be diagnosed with chlamydia for an astonishing fourth time, clinic staff provide sexual health care for the inmates of maximum security jail HMP Manchester and, after a drunken one night stand, 26-year-old student Ben tries to persuade his girlfriend to lift a sex ban by proving he's still STI-free.

Twenty-year-old Gary finds out the hard way that it's not just STIs condoms are designed to prevent. Pre-op transsexual Jasmine hopes her high-risk sexploits don't jeopardise her life-changing operation.
