Talk to your partner about sex and drug use!
Talking about sex can be very difficult for women. It is not always safe, either. If you are in a situation where your partner could be physically violent or is physically violent toward you, your first step is to get help. Talk to a professional who can support you in making whatever changes you need to ensure your safety.
If you are unsure about how to begin a conversation about sex and drugs with your partner, there is plenty of help. You can attend a safer sex workshop in your community.
