am aware that my wife has a toy, but we have not talked about it. I don't think she is aware that I know. I have noticed a change in my stamina and can see a difference in her pleasure. I want to introduce her toys into our intimate moments without making her feel uncomfortable or self-conscious about owning them, as she can be sensitive about her sexual drive.
Edit: she grew up in a community where women are shamed for having a sexual drive. That is why i believe bringing up the subject casually will make her uncomfortable.
