Talk to your partner about your interest in sex toys. Make the conversation fun, not scary. Like all technology, sex toys are an extension of the body. They are hands, tongues and genitalia that are bigger and stronger, and never tire. They are tools that help us give pleasure to ourselves and to each other.
Sex toys can be equally great for partner sex and masturbation.
Any sex that can be improved by something that probes, stimulates, squeezes or alters sensation can be enhanced by a sex toy. Others are concerned that their partner will feel inadequate. But this is like feeling self-critical that you need a comfortable chair to enjoy a movie. Our shyness about using sex toys really expresses the shame we feel about admitting we're sexual in a sex-negative culture. It's no illusion.
