Any recommendations on ones that are small enough to sit on but without the danger of an ER visit.
I'm sure it's been mentioned in every discussion pertaining to the technical details of anal plugs, but according to everything I have seen, you just need the base to be at least as wide as the maximum diameter of the part that goes inside you. This will supposedly keep the base on the outside and prevent the toy from being "swallowed." But do not hold me to that, because there are so many butt plugs out there that some shapes might be prone to being "swallowed" despite having a base that is larger than the maximum diameter of the head. The smaller versions of the plugs with the crystal on the outside of the base, for example, are said by many who have used them to be so small that they are prone to slipping all the way inside. So don't get something too small.
I want to get one of these:
Right now, I have one of these (it's ok but I don't like how it's two sections as much as I thought I would, and I wish the "neck" was shorter so that the base would rest flush against my body and not extend out from between my cheeks when the plug is in place):
From the same place, I also have this glass dilator which is a lot of fun to use anally, even though it is not a plug so I can't just leave it in and go walk around with it inserted:
I used to have one of these plugs, which is a great shape and great for beginners but I wished it was wider:
I also had an njoy plug in the XL 2.0 largest size available but I didn't like it. The head was too short and the neck was too long, and in my opinion the curve is pointless on a butt plug because a plug is stationary and not being thrust in and out like a dildo.
