I recently bought this one and it was fun to use with the guy I was seeing at the time. I found I needed to squeeze my half more than just thrust into it to get the right sensations but it was a good. Just make sure you turn the blow hole up face on it or you’ll get lube and cum dribbling out all over the place.

The Fleshlight hole was pretty small so we didn’t use that but there are similar toys that do work well. We had a double-ended sleeve that was great. I don’t remember the name.
I haven’t had a chance to try these with a friend yet but I’m looking forward to it sometime. Both seem like they’d work.

This one has a pretty wide hole that would probably stretch enough for 2 guys to DP it.

I’m recently dating a guy who’s into frotting. It’s never been something I really tried much but I’m getting more into it. We also have tried sounding together and that’s a lot of fun. I picked up this thing and it’s fun to use while we make out.

Keep looking and don’t give up!
FYI this also already exists. It is totally large enough to fit two cocks. I bought it in March 2020... and haven't been able to actually try it out yet though, womp womp
