Of course he knows, he lives with me. He finds it quite fascinating and supports anything I buy and doesn't even mind if I use them solo. I have him help me pick out lingerie he likes to see me in, talk about some of the articles I've read, valuable information that has helped us both in our sexual relationship.
He knows, and he loves that I've found a way to get cheap/free toys to play with together thanks to the points system. I don't think we could have afforded to get all the toys we wanted to try without it.
My husband knows I'm on here, and I've bought him things from here before. If I see something interesting while we're sitting around (like right now), I'll flip my computer around to show him a picture & get his opinion.
