This may be coincidence, but we have been using Silky Sheets
Mystical Musk aroma for a couple of years. I find that when I am using it a lot, I seem to have orgasms more easily. I've been using this product on our sheets intermittently for almost two years, and I just made the connection 6 months ago.
It could be a coincidence, because my orgasm response is all over the place. But, it seems to be a connection. It doesn't seem to do anything for attraction, I'm monogamous and only My Man and I sleep in our bed. But, this weird side effect seems to happen. I'm not complaining.
I have to say, be careful of the scents of this product. The Vanilla Fields is disgusting! But, the Mystical Musk is wonderful, it takes the "just had sex" aroma out of your sheets until you can change them, and it seems to help me with orgasm.
I don't know about any other product that claims to do this.
