We have a couple of the Mega Mighty Penis Extenders and absolutely thing they’re worth the try. Surely can’t be a bad idea to start on the smaller end to be sure, unless your wife has experience with larger toys and you know she wants to go that direction. Here’s my review of the 2 Extra Inches extender that is our most-frequently used. We also have the Extra Girthy but she has to be in the very particular mood to take that one and I just used my VIP reward code to get the 3 Extra Inches - haven’t used it yet, but looking just out the box I don’t see how it will be an inch longer than the 2. Even if it’s not bigger, I can’t complain about having a spare around for when the favorite eventually wears out.
I’ve provided quite a few other comments around playing with extenders outside the review if you want to skim them here.
We got this rabbit-ish vibe as a tester a bit ago and is my wife’s favorite of the many that variety we’ve tried. It does take a little more lube than we’d normally use as the silicone has a little drag on it and tends to catch more than some others.
