At 3.5" and beyond any extra 0.1" wide is huge - even circumference where 0.1" diameter = 0.314" additional circumference, even adding 0.1" circumference can be felt.
I've got the Destructor butt plug - but it was too long so I cut the top off, not great shape now and its kinda tacky, like its dissolving 😢 It's not a good product. However it was about the largest thing i've ever had in I think, but the narrow part isnt 'long' enough to keep it in. Had to use my hands to keep pressure, unfortunately. So not great. Supposedly 3.8" wide? Not sure it's that big. (Circ. listed is 11.6, that'd be 3.7". Possibly I got that much in 😃
The thing that attracted me to it was the very wide 'narrow' point. I want to be kept open at least 3". Tantus Tex slims down to 2.25" and while for long term wear this is ok (my record is 6 hours), it's not that big. (My wife's taken cocks that big in her ass and she's not very pro. This is an amateur size! 😃
I have the Cyclops plug and it's a little tricky to get in at 3.5" wide (11" circ.), the shaft is 10" circ and slides down easily. Too bad it's so long - it bottoms out with 2-2.5" to spare. If it was that much shorter, I could wear it!
Trying to find a plug that keeps me open at least 3" wide, or a shorter dildo so I can wear it in tight pants/cycling shorts or something. But in the 3.6-3.8" range (can't do 4", I think my pelvic bones wont allow it). Suggestions?
