Searah says "When engaging in backdoor fun, a good lube is essential for safety and fun. We usually recommend a thicker water-based lube like the ones below, but if you have lube you like, but all means use it... and lots of it! You'll notice that we do not sell any lubes with numbing agents. Our belief is that numbing agents can lead to anal sex being less-safe as pain is your body's way of saying SLOW DOWN or STOP! So stick to a general lube and take it slow. If you want more info on backdoor safety, you can check out our Anal Sex 101 here"
