Masks are a type of sex toy that can be used to add a new level of excitement and mystery to your sexual activities. To use a mask in bed, you can try wearing the mask yourself or asking your partner to wear it. This can create a sense of anonymity and can make the experience more intense and exciting. You can also try using a mask as part of role-playing or other types of fantasies. It is important to communicate with your partner and make sure that both of you are comfortable with the idea of using a mask before beginning. You should also make sure that the mask fits securely and does not obstruct your vision or breathing.
