Masturbation is MEDIUM RISK
When practised between partners, masturbation is a medium risk activity, but is a no-risk activity if you do it alone.
If you masturbate by touching or being touched by a partner, you can reduce the risks by:
• being careful not to spill any semen
• using plenty of condom-friendly lubrication
• avoiding touching the eyes, mouth, nose or any broken skin after ejaculation.
