Not really. There is such a huge variety in material, size, and shape that you need to something that is fun.
Just be aware that not everything out there is a safe product in any scenario. In the case of buttplugs: If you plan to wear it for longer periods of time, get one that has no chance of getting lost in your butt.
And by longer times I mean anything that is not you actively playing with it. I had one of those and was sitting on a cushioned chair when suddenly something felt off. Luckily I grabbed the immedialy after it vanished, otherwise it would've been a hassle with ER digging it up.
In general: Everything where the cross section of the base is not significantly wider than the thickes part of the plug is not safe for "unattended" wear.
I say cross section bc the base does not have to be round. A "strip" works usually better than a full round base bc it is more comfortable while wearing.
These two are good long-term wear examples. Not endorsements, I do not own either.
