My current inventory:

• Tantus Ryder plug. Meh. The handle kind of irritates my perineum. Girth is nice going in, but once its in, I barely notice its presence aside from the handle.
• Tantus Protate Play plug. Pretty good as a straight up plug without the bullet, as the vibe is underwhelming. For vibes, I want something that hits harder & slower, with more variability in pattern. Can't comfortably sit down with the bullet in the plug, but it is nice for playing while laying down.
• Tantus Curve dildo. I like the size; length and girth. The angle and rigidity makes it occasionally inconvenient for play, only certain angles & orientations work. I like that it has a bit of passive suction on the base, I can slap it on the wall or furniture and go to town, but the base is a bit too big to fit on the subway tiles in my shower.
• Rodeo Brief harness for when my wife pegs me

Ok, so with that out of the way: I'm looking for a dildo. Although all of my current toys are Tantus, I'm not really interested in buying more of their stuff. I'm not interested in going bigger than my current Curve. I'd be happy staying at roughly the same size, maybe even downsizing slightly.

Is dual-density really THAT much better than single? I've not yet been fucked by a guy, but I'd love for my next dildo to feel as real as possible. Harness compatibility is a bonus, but not required, as most use would be solo. Vibration not really required, and probably wouldn't use it.

Any recommendations?
