I really don't have a certain time I use them. I don't plan it and it's not something I do a certain amount of times each month, so it really depends. This month, I've used none. Last month, I used Sweet Lola many times, Pure Wand, Vitality and a bullet. So it really just depends on the setting and my mood. I certainly don't use them each time we have sex though. We like to put some foreplay in the mix, not just rely on vibrators.
