tldr: I'm at 18cm now which is about 7.1 inches, erections are very strong

After buying my first electric air-only pump (first picture) I went a little penis pump crazy and bought a bathmate and also a second electric pump (2nd picture) that works with water. The water electric pump didn't let me set the pressure - it's set to pump up to about 35 kpA so I set it away for a while and focused on the bathmate.

It took me a while to get the bathmate working consistently. It still takes me a few tries to get the suction on really good. I still also have trouble with air getting in the cylinder. Still when it worked, it worked well and I felt like my dick got a quality workout and stretch. I once got a really good suction and left the bathmate on for about 30 min. Afterwards I had my first donut around the head. My girl called me over later that afternoon and I was worried about going with this donut. I decided to check beforehand if my member still gets erect properly with the donut and it did. But when I got over there I didn't account for the fact that the condom wouldn't fit over the donut! A few weeks later the hand pump stopped working so I decided to give the electric water pump a second try.

I have a hard time going in erect. I don't have time to watch porn and it's been convenient for me to use the bathmate and the electric water pump in the shower. Maybe most of you already know this but I realized that the best way to use the electric water pump is to take the rubber flange off and slide it down your dick, then fill up the tube with water and then insert your dick with the flange in the tube. Once I realized how to use it properly, it's been way better than the bathmate.

It regulates and maintains the pressure at 35kpA so I don't have to do anything. Once it's above 30kpA that's enough suction for it to hang by itself without me holding it as well. I can't dance around with it on but it's secure enough that I can focus on showering. It gets my dick up to the 18cm mark pretty quickly so I've been able to get in some good sets while I shower. Since it works so effortlessly I've been very consistent with it and my erections are getting super hard.

Three months ago I was barely hitting the 17cm mark on my first electric air pump, but I'm now consistently hitting the 18cm mark on both pumps. I haven't been measuring the girth but it does seem like it's gotten thicker. However I'm not sure if my cock actually gets that long when erect during sex. I've been meaning to stash a pocket ruler to inconspicuously measure it the next time around.

Still I'm also noticing that I'm able to stay hard longer even after cumming. There was one time where I got it back up after 10min of having sex and we went at it again. So I've become a full believer in pumping.
