My lube is Maxidus. Supplied by Lovehoney UK. It is clear water based and safe. I have a small 40ml plastic bottle...an airline type Whisky/gin container. A small rubber topped screw-on dropper fits perfectly. Firstly, i half fill it with the lobe and I have discovered that by adding just about a third of the lube volume with boiled,cooled water and shaking it well, makes a very goo lube indeed..
For the aneros, I put a drop of KY jelly and spread it evenly over the surface. It slides in easily. The lighter slightly diluted Maxidus, it very smooth and let's the toy slip easily around the prostate.
I have had my best results with that. My position is the classic,lie on my left side and draw up my right leg to about 90 degrees supported by a cushion to give room for the penis to erect freely. Hope this might be helpful . Ps. in the UK, Maxidus costs £9.99. For 250mls.
