I got one about two years ago it looks ok not real but under panties it looks great.My friend can penatrate and says its as close to real for him, its wonderful for me also so i am not doing anal.
To answer your questions
#1 yes a few years ago
#2 I got the one that i can pee thru and penatrate, Putting on is eazy it has a hole at top so slide your penis thru and slide up to waist the take strings around and hook the knot then take bottom string up under and tie at back.make sure you use corn starch to keep it from rubbing you the wrong way
#3 the quality is great has not tore from use yet
