I know this has probably been asked before but I'm not having any luck searching /r/sex for it. My wife currently has a Feeldoe for pegging fun but she's looking to get something that feels a little more secure. Any couples recommend a good harness (and maybe accompanying dildo) that they have found enjoyable for the ladies to use on their men?

We are currently looking at something like this but not really sure what information we should be looking for. Thanks reddit!

EDIT: I should have said that we don't need a double-dildo like the Feeldoe. I was just saying the Feeldoe is the closest we have to a strap-on right now but it can slip out during the fun.
