Since you both use toys and know about each other having an account that's fine. If my mom were open about it and liked the kinds of things I liked, I would be happy to talk about it. For me though, my mom tries to keep her things a secret, and I was a big grossed out when I found her drawer. She doesn't have much, or anything too fancy, so I know shes not really into toys at all.
She has no idea I use this site and that I use toys. She knows I'm sexually active though and since we don't get along about certain other things, I really don't feel comfortable mentioning it to her or suggesting things for her.
