Curious about butt plugs lately as I have seen them for sale at various websites. Was thinking I would like to put one in my wifes ass and then fuck her doggy style thinking I would be able to feel it on my dick. Seems this would be the closest thing to doing a DP with her (which no chance in hell she'd ever do). So...what experiences do others have with butt plugs? How long can they be left in place? Anything to be concerned about?
