Lubricant is essential for comfortable and better sex, but when it comes to anal sex, lubricant is the single thing that makes it possible and pleasurable.
Whilst ordinary lubricant is better than no lubricant for anal sex, you are better off with an anal lubricant, specially designed for the job.
Anal lubricants are thicker and less runny than regular lubricant, and this makes them easier to apply and position. You can also blob them onto your anal sex toy or finger, without it running all over the place – allowing the toy to glide into position much easier.
