I’ve owned Aneros devices for 5 years, playing on and off but never getting much out of it. Until last week. I had not been able to find my MGX for a long time but re-discovered it during a move. Found some time to give it a shot and while it always felt good, I never got any p-waves or into the feedback loop. This time was different, within about 2 minutes I was feeling the p-waves and my limp penis was twitching, after about 5 minutes my penis started hardening as I started getting some bigger waves but I was having trouble holding the contraction level to keep it going. I could adjust and find that level again for the next 10 minutes and then nothing. If I completely relaxed for a couple minutes I could get back to twitching but nothing like what I was getting at the beginning. Is this just because my sphincter isn’t strong enough to keep up the contraction at the level I need? Any suggestions to keep it going?
