If you use sex toys alone there is no risk from sexually transmitted infections although you should still be sure to keep them clean to stop bacteria and viruses.
When using sex toys, you need to be careful not to hurt yourself or your partner with them. If you use something that’s too big, you could rip or tear the skin inside the vagina or anus. Sex toys can break during use and damage the genitals or become stuck deep inside the body.
Prolonged use can also damage the skin of the penis or around or inside the vagina or anus.
If sharing sex toys, bacteria, viruses and parasites that cause sexually transmitted infections can easily be passed between partners. Find out more about sexually transmitted infections (STIs)
