Stimulation should ONLY be applied below the waist
You should also ensure that your chosen electrodes are fit for purpose (ie: don't use a probe for anal stimulation unless it is stated as being suitable for anal play).
You should not use electro sex if:

• You are pregnant
• You have epilepsy
• You have any sort of heart condition (including pacemakers)
• You are suffering from any sort of genital injury or disorder
