I'm considering this glass butt plug as a gift for my wife (who only likes glass plugs). I've bought a t-handled plug from this seller previously, and it's an absolute work of art. He's been handcrafting glass sex toys for over 20 years. I'm interested in the plug I linked though, because it keeps the sphincter widely dilated when it's inserted.

I know T-handled butt plugs are the safest, but I don't see how you could even have a t-handle on a design like this. (If you could, he would offer it – he offers multiple base options on other designs). This would only ever be worn during sex for 30 minutes max, not while walking around or sitting. Would this be low-risk enough given that? If not, are there other glass options that stretch the dilate the sphincter that would be safer?
