So me and my GF have admitted to each other that she likes some anal stimulation and have bought the right lube, some plugs and some other toys. Occasionally we use them, but she really needs to be in the mood.
Since we started, over the past year(s?) I gained an insatiable curiosity to what anal stimulation feels like. I read a lot about the male prostate and the pleasures it can give. I started slowly with just a finger, but really liked it and soon enough I desired bigger and bigger things. Moving to a small plug, then a bigger one. Then I decided to get a glass anal dildo in the shape of an “icicle” (basically small bulbs stacked on each other, growing in size), with the excuse “it will help us train your ass to take bigger things”. This really did the trick for me and could easily touch my p-spot.
Now, my GF did not know about this, I have mentioned to her that I was interesting in trying anal stimulation as well, but she made it clear that she doesn’t want anything to do with my butt (sadly), thus, I continued on my own.
