1. "I care about you and want you to be safe and healthy. Have you considered using protection like condoms during sex?"

 

2. "I understand sex can be complicated. But protection is really important to avoid any unwanted outcomes. Have you thought about what you would do if you got pregnant or contracted an STI?"

 

The key is to express your concern from a place of caring for your friend's health and wellbeing. Avoid being accusatory or judgmental. Focus on the importance of protection and the potential consequences of unprotected sex. Your role is to provide information, not dictate your friend's choices. But coming from a place of love and compassion is always best.
