My nearly 17 yo son has been with his girlfriend for 2.5 years. I believed she started taking the pill last year but now find she didn't continue after 3 months. My son says it's not a problem as they don't have sex. I have given him condoms but I am very uncomfortable that there is no other contraception in place. Additionally I am concerned if they are not having sex(!) because that doesn't sound very healthy to me. Do I open the conversation with his gf? Who is very introverted and struggles to talk. Help!!!!
