This has to be the BEST butt plug out there. The ball keeps it secure and up my butt all day. Other butt plugs have fallen out, but this one stays secure through a variety of daily activities. I love the feeling that it gives me when worn. It gives me a constant reminder that I have a butt plug inserted and to me this is ******, especially when I'm doing such mundane things as grocery shopping, etc. Also, when I wear it, it gives a very low grade arousal to my ****, which is magnificent. I highly recommend this butt plug to anyone, male or female, who gets aroused by the feeling of an object in their butt hole. Can't wait to get the medium sized Round Butt-Plug!
