What Size Butt Plug Should I Buy?

Whether you are a backdoor beginner or you are more adept in the anal arts, choosing the right size butt plug for the occasion can be tricky. First and foremost, you want to make sure you are comfortable, but you also want a good level of stimulation — that’s the whole point, after all!

But first, you might be wondering why would you even want to use a butt plug in the first place?

  1. The anus is rich with sensitive nerve endings that respond to different types of stimulation, such as touch, heat, pressure, and friction, all of which can feel extremely pleasurable.
  2. The full sensation from a butt plug provides internal stimulation. For people with penises, butt plugs can stimulate the prostate, which can give you a prostate orgasm. For people with vulvas, butt plugs can enhance stimulation of the vaginal canal, which can feel fantastic when paired with vaginal penetration.
  3. They can be worn in public or as you go about your everyday activities for some added kink. The sensations from the plug as you move or simply knowing your sexy secret can keep you aroused throughout the day.
  4. They can be used in BDSM — a dom may require that their sub wears an anal plug.
  5. They can be used for anal training to prepare you for anal sex or larger toys.

Butt Plug Anatomy

butt plug features

While there are endless exciting design features to choose from, all butt plugs have some similarities. Starting at the bottom — seems appropriate, it is absolutely vital that any toy you plan to use anally has a flared base to prevent it from being fully inserted, traveling up inside you, and requiring a visit to emergency to care to retrieve it.

Next, there is a neck that your anal sphincters will contract around, holding the plug in place, followed by the body of the plug. Butt plugs also have a tapered end that makes for easy insertion.

The two measurements you need to think about when buying a buttplug are the insertable length, i.e., how far inside you it will go and the diameter or how wide it is. Some websites use diameter (the measurement across the width of the plug) and some use circumference (the distance around the outside of the plug), so be careful to check which one is given.

We’ll talk about the diameter today as it’s easier to picture but if you want to work out the circumference here’s how you do it:

Circumference = diameter x π, or 3.14

This chart is an estimation of different butt plug sizes, but just like clothing sizes, not all shops will classify small, medium, and large in the same way. This means it’s super important to always check the measurements, as you don’t want to be left with something that’s too big to even attempt or too small to bother with.

There are no hard and fast rules for choosing butt plugs as every butt is unique. As well as your physiology, how comfortable you feel will play a factor in which size you should choose. If you are nervous, you are likely to tense your muscles more, making it better to go for a smaller size. With anal play, it’s always best to go slow and steady. Start out with a smaller plug, get used to that, enjoy it, and then move onto a bigger size if you want to!

With time, both brain and booty will relax as they realize that everything is A-OK and this is actually pleasurable.

What Size Butt Plug Is Safe to Wear All Day?

Sure wearing a butt plug is a great way to add a little spice to your household chores, but generally, it’s advised that you don’t wear a butt plug for more than 2-3 hours at a time to limit the possibility of damaging the tissue by limiting the blood circulation. Do people wear them for longer? Yes. Is it recommended? No. You can still get the thrill of being plugged in public or as you go about your everyday activities, but remember to give that booty a break and always check for signs of irritation or damage. And, of course, if you notice any pain or bleeding, take your butt plug out immediately.

If you do want to wear your butt plug for a few hours at a time, there are some features to look for:

  • Soft silicone is the best material as this will be much more comfortable, especially when you sit down
  • Opt for a thin flexible neck, so that your sphincters aren’t too stretched
  • A t-bar base will be most comfortable as it can the base can sit comfortably between your butt cheeks

Tips for Using Butt Plugs

So now you know exactly which size butt plug to buy, here are some tips for plain sailing on your first voyage!

  1. Always start small — both in the long game and in each session. Start by massaging the anus and then use smaller toys or a finger warm-up before using anything bigger.
  2. Lube, lube, and more lube! Unlike the vagina, the anus doesn’t produce its own lubrication so lube is essential. Lubrication applicators are fantastic for making sure you are fully lubed up and ready for action. Just make sure whatever lube you choose is compatible with your chosen butt plug. Water-based lube is best with silicone sex toys but will need to be reapplied more frequently, whereas silicone lube can be used with metal or glass butt plugs and is slipperier.
  3. If it is your first time using a butt plug or anal toy, you might want to try it out in the shower first. The warm environment can help you to relax making insertion a lot easier. It will also put aside any fears you have of getting messy.
  4.  Practice safe sex. If you are sharing sex toys with a partner you are not fluid-bonded with, cover the toy in a condom.
  5. Be sure to clean your butt plug thoroughly after use.
  6. Always listen to your body. If you feel pain or notice any bleeding at any point during insertion or while you are wearing a butt plug, stop, remove the plug and assess the situation.
