I’m also happy to try out new attachments as my partner and I do lots with straps. The Fusion, Glamour Pleasures by NS Novelties is Clear (it also comes in Aqua and Pink). This is a higher grade jelly so it pairs well with most lubricant types (yay for silicone lube). Although it may not have been intended, this does well with the G-Spot! It fits the O ring attachments wonderfully and also works alone and tends to “suction” to hard surfaces. The great thing about this is that it works well vaginally or anally, so it’s great for all! The insertable length is 5.25 inches.
