Picked up a knockoff Aneros SGX at a sex shop yesterday (Put them side by side – identical but much cheaper). I am a smaller statured white guy (5'7" 140lbs) so I thought the SGX would be good as it is supposed to be popular with asian males.
So of course I had to give it a try last night. On insertion it created a massive erection and a pretty high burst of arousal – but the arousal faded in seconds, and the erection faded fairly quickly too. I left in in for maybe half an hour, chilling on the bed, but nothing happened. I clenched and unclenched and felt a little something, but the only significant feelings came with pulling it out a little and letting it slip back in.
So far the story is unexciting but then my wife came in to ask how the "butt plug" was working. I told her it was lame so she suggested we try it while we fuck. Of course I was up for this. Once we got started the Aneros seemed to come into play, I could feel some extra feeling perhaps once the prostate started to get aroused. I was ultra hard and had so much lust and drive like I used to have in our pre-baby days, I totally got lost in the sex but after a bit I didn't really notice any sensation coming particularly from the Aneros itself – just a general boost in intensity.
