Is my tube too narrow or sessions too long?
I’ve been using a pump sporadically for a year, so I don’t have that much experiene even though I have owned the pump for a while now. I followed the instructions on LeLuv’s website for sizing, but my measurements were hard to be certain about. So I thought I would describe how a session goes to see if experienced people might be able to assess if I’m doing anything wrong.
All the vacuum measurements are in kPa.
I begin at 5-10 kPa, and the skin touches the full circumference about an inch up from the base and also along the tangent of the curve of my penis.
After 5 minutes or so, I increase the pressure to 15-20 kPa another 5 minutes or less.
Finally I increase the pressure to around 25 kPa for 5 minutes intervals, and briefly switch to a program that repeatedly spike the pressure to around 40 kPa before immediately releasing. I don’t do the spiking for long, because the electric pump starts getting warm - maybe 2-3 minutes. I keep alternating with 5 minutes of the 25 kPa and then a 2-3 minutes of the spikes for the remainder of the session.
As time goes on the skin is in contact around the full circumference further from the base, and about 25-30 minutes from the start the skin is in contact almost all the way to the ring of skin behind the head. When I end the session the penis is a little difficult to remove from the tube. It comes out with kind of a slurp due to being in contact most of the length.
I’ve found that keeping the whole session under 30 minutes prevents the donut from forming behind the head of the penis, but there is a flabby blubberiness making the penis appear fat for maybe 30 minutes or more. Around the 30 minute mark and beyond the donut appears and can linger for hours after the session, so I try to keep that from happening by limiting the duration to 30 minutes.
Sorry for this being so wordy, and I hope it makes sense. Just wondering if my tube might be too narrow or if my sessions are too long. I don’t get the donut, but I do get the tube packed and the fat blubbery penis for awhile afterwards.
