A bit more in-depth review (no pun intended). After working my way up, I found the Snug Plug 4 to be my go to for warming up, wearing for extended time and out in public. Don’t be shy with the appropriate lube for silicone toys. Once in, it is perfect for me in terms of insertable length and fullness. The thin neck is extremely comfortable. Tried the vibrating Snug Plug 4 and found it to be even more pleasurable, especially on the low alternating pulsating vibration. It builds over time. Truly. At first, it’s like this is nice. After about a half hour, it’s more like this is really very pleasurable and distracting in a great way. Then decided to move up to the vibrating XL. Didn’t think the extra half inch in diameter would be that much of a difference, but it really is. Took a little bit more to get it fully inserted, use enough lube, and once in oh my even before I pushed the remote. Once on, intense pleasure, like nothing I have felt before. Low, alternating, pulsing and rimming completely put me over the top. The most incredible orgasm I have ever had. I’m no expert, but the diameter is probably not for beginners. That being said, if you are looking for anal pleasure, this is by far my number one choice by a mile.
