Kelly Osbourne de-stigmatized sexually transmitted disease testing in 2008 when she candidly confessed to getting regularly screened for STDs. She has also revealed that she saw a condom for the first time at age 7 when they were distributed for free at her father’s concerts. When she asked what they were, her mom explained without hesitation. It’s never too early to have age-appropriate conversations about sex, says Murphy. Having such conversations as often as necessary over the years makes you more approachable than waiting to go into a room for “the big talk” and exhaling a sigh of relief when the conversation is over, she says.
