Hi, hear is my take on this. I have been into anal play now for five years and have now decided to wear a butt plug 24/7. Like your self I did all the reading I could fine on line and in books with a trip to my doctor to ask him about it. Once I was sure this is what I would like to do I ordered the Jiuai butt plug, this is made of 100% medical grade silicon. It is large at 12 CM long and 4.5 CM at its widest point.
I first tried about 8 water based lubes, and the one that I found that work best is Astroglide gel with a price tag right around $8.00. But even with this I found my self re lubing about every three to four hours. Since this is a silicon plug you can not use a silicon lube but you can use a oil base, so I moved on to coconut oil, pure and unrefined, 100% organic by Carrington Farms. Not all lubes are healthy, this one is. I found that even with this I was re lubing every 6 to 8 hours and a real mess to carry around with me in case I had to remove it to use the bathroom.
I found that I had to do more reading on this subject and hear is what I found, Never ever use a jellie type but plug, and if you go with glass be ready for that trip to the E.R. Start with a small long term plug and work you way up to a large or even larger like a 2.0. If you go with the Rose bud start at the top with the 2.0. if you start with the medium that could mean a trip to the E.R. Remember your butt is like a vacuum, it like to suck everything in.
About a month ago I ordered the Njoy pure plug large, OMG what joy it has been. I use Wet platinum silicone lubricant about three drops on the plug every morning and it goes right in after my shave and shower with no re lubing. All and all about a hour each morning I am not wearing my plug and have been doing so for the past 6 months. I went back to my doctor yesterday and he says every thing is fine.
