I’ve tried everything from water-based to silicon. Coconut oil and shea butter. Nothing seems to stay slick more than 15-20 min. Vaseline is the only thing that seems to let the toy glide for a long time without having to re-lube which ruins the moment for me. Are there any studies that show that it is bad for your body? Or is it all speculation? My body just seems to absorb lube extremely fast.
