What do but plugs do? Do you keep them in during the day as you work etc. or are they strictly for massaging the prostate?
hmn... so a butt plug is exactly what it sounds like, a plug like sex toy that you inset into yourself, and generally shouldn't be worn for any longer than 3 hours at a time (though overnight is an option for some). based on how you can tighten and loosen your anal sphincter, this also means you could easily be poking into your prostate at your leisure with one in. doing so would massage it, and in a case like yours, help to reduce it's general size over time. always use lube, and of course, over time you may want to use a larger plug. non-porus ones (metal, ceramic, glass) are great for longer term ownership, and use. they also need much less lube , water based or otherwise, and won't retain any smells either after you've washed them off with soap and water.
some use them as a "trainer" for their asshole to be able to handle anal intercourse easier, especially for what's supposed to be the average penis (1.5 in diameter) though the actual handle and connecting point are not that wide. I'm really partial to some of the ones I've picked up that are metal, mostly the Njoy ones from Pinkcherry.ca though I live in canada in the first place. starting small is a good idea, especially for those who identify as being straight
(though I really wanna point out, all men have butts, all men have prostates, it's not an exclusively homosexual thing to want pleasure, it's only homosexual if that pleasure is being provided by another male that you want to be pleasuring and pleasured by)
the one below is the medium njoy plug for refrence, and said website. I use the large one, and ones that are even bigger.
