Back track?

So latley I have been having unsuccessful attempts with my Aneros. Im not getting discouraged because I know it will happen again. But in all honesty I am still un sure what I am doing wrong. My first guess you can call it Super O was fantastic and I really wish my leg didnt get a cramp lol. But like I said my last few attempts have been let downs. I do everything the same and maybe I am just not in the right frame of mind. But I have some questions which I know might help my future success.

#1- Im using "Wet" the water based lube, I know outside giving you the runs after a while of use it's not to bad. Would this be a right choice for a lube?

#2- My first success was laying on my back, I actually enjoy this position best and being new I find it more comfortable. I know the instructions suggest laying on your side, but to me that just breaks concentration. Is this position maybe not my forte?

#3- It seems the P-tab might be on the right spot but I am still getting accustom to the new feelings so I may not have quite nailed it yet. Is there anyway easier to find the "Sweet Spot"?

#4- After insertion I lay there for a few minutes, I've grown accustom to
it being up there so it only takes me that few minutes to relax. Should I wait longer?

#5- I start with mild contractions and some light breathing. Now Here's what might be the problem, and I've read the sticky's on this but maybe I dont get it. I contract in like trying to stop from taking a leak and hold it for as long as my muscles will let me. Sometimes this feels pretty good but nothing to get over excited about. I have only had one time where it felt like the Aneros took over. How can I get the involitary contractions to take over?

I know you should stick with success but I've read so many great things about the helix that I want that to be my next investment. Im currently using the SGX, I was able to purchase the Eupho but after reading what B Mayfield said as an expert weapon I will upgrade to the Helix and save the Eupho for when I get more experience. Any suggestions or help would be greatly appreciated.

Thanks
