STIs can also be passed on through female to female sex, so lesbians should always practise safe sex by using female condoms and dams. Recently the first case of female-to-female sexually transmitted HIV was documented, with the main risk thought to be overly vigorous use of sex toys leading to blood exchange. There is also a risk of transmitting Hepatitis C when sharing sex toys that might cause tiny nicks or cuts, especially during menstruation, so always practise safe sex and use a condom.

Keep your sex toys clean by wiping them with a damp, soapy cloth and letting them dry off (bacteria finds it difficult to survive in clean, dry conditions). Any plastic attachments can be submerged in water, but don't let the part that holds the batteries get wet.

Putting a condom on brator will help keep it cleanest - and safest. Even using a vibrator with a condom on yourself will ensure you don't reinfect yourself - or your partner - with an infection you've had in the past.

Most people enjoy using a lubricant with their sex toys. The best lubricant to use is a water- based one, such as KY Jelly or Wet Stuff. Oil-based lubricants, such as Vaseline and baby-oil, weaken condoms and increase the risk of breakage. Water based lubricants are also the easiest to clean off sex toys.
