Not seeing any girth expansion in pump

I’m no pro, but what I’ve found that helps me mostly is heat and arousal. Heat before, heat during, heat after, and heat during rest also.
This week while my wife was performing her wonderful duty of cock worship and fellatio, she noticed that my shaft was noticeably thicker. Of course, I had a glorious hard on which benefited me in the girthiest of ways, but her small hands looked even more delicate and feminine as she gently fondled my manliness and caressed it with her lapping tongue and devouring throat and accepted my manhood all over her face…

I’ve been enjoying warming up to my usual 3Hg for a few minutes and then pushing myself to my upper limit of 5Hg for only a second until returning to my comfort zone of 3Hg. I do this maybe 5 times. My entire session lasts maybe 5 minutes. Coupled with this, constant heat a mentioned by others, even if it’s many hours post session or the next day. I use a hot water bottle folded over with a protective cloth pouch when it’s a little bit too hot and try and stay in for 15-20 mins, or until it’s no longer warm enough. Baths work well for me, but to get the water hot enough becomes almost unbearable for the rest of my body.
Keep trying different things safely and you are sure to find something that works for you!
Bonne chance!

Funny how differently we feel. 3Hg is hardly noticable for me and 5hg barely feels like it’s productive. 7-8Hg feels like a good middle ground. I’d love to go above 10Hg all the time because it feels very productive but I know it’ll just give me insane fluid build up if I do it for too long. I’ve had a 6.7” FG donut after pumping but I know that’s not a good thing. Trying to keep it reasonable and consistent.

1” longer than your BPEL? Thats insane.

That which I have found is most important is heat. However I ensure that I also jelq in between sets which I believe places me in great position for expansion during my sessions. Wishing you well.

At lower pressures, I also wasn’t seeing much expansion. I somewhat slowly and carefully have worked myself up to a routine that involves starting at 4 Hg for 10 minutes. At this pressure, there is just a little expansion in girth and length. I then step it up to 6 Hg for 10 minutes and then 8 Hg for the last ten minutes. By this this time, my penis is fully packing the cylinder and I don’t feel the least bit uncomfortable, usually quite the reverse, it feels good and I may leave it in for another 5-10 minutes. I am experiencing some fluid build up but no negative Pis, only positive ones. Like others, I recommend you incrementally test more time or more pressure in the tube. As also recommended by others, I use constant heat by way of a heat pad wrapped around the tube, set at high, too.
