I currently have an SGX and am under 5'5". I have been using the SGX for 6 months and get good feelings from it however haven't had any dry o's yet from it. I wanted to upgrade to a new model, figuring that it may help bring on the dry o's sooner. Maybe I'm jumping the gun on this. I was thinking moving up to the helix or progasm jr as they would probably give a more aggressive massage. What's the logical next step up from the SGX?
The Progasm Jr. gets my vote, though not so scientifically. It's my one and only, so I have nothing for contrast. I will say, I arrived at the Super-O within mere weeks with it.
I might suggest Helix Classic as your next step to see if it meets your desires...however for me size is not the most important variable...I have had Super Os using my Peridise. The Helix has many users with excellent results.
I agree with Jaxsun. Helix Syn might be another, however, more passive and subtle than the Classic model. I have most models and go back to the Helix Classic quite often. It works everytime!
Jaxsun and G-Force both have excellent suggestions. However, the most logical "upgrade" from the SGX is the MGX. ...Or if you just want to feel the pressure, my favorite of the larger models is the Maximus. It gives strong, constant pressure, without poking or becoming uncomfortable like the Progasm Jr can.
I think it good to have 2 to switch so you don't get bored.
