I mainly pump because it’s just damned fun.
I still need to make a thread proposing my new measurement for a cock which is.
PPEL or pump packed erect length.
My pump digs in basically bone pressed and I find it’s a good way to measure my length. in the pump.
I leave my dick in for up to an hour at a time, it’s fine, remove for 60 seconds, massage and put in again, mine seems to be very resilient to pressure (so noobies, don’t do this) I’m not even trying to push myself, it just doesn’t really hurt that much around 10hg for an hour, more at the base where it digs in more than anything.
Anyhow in the pump I can get a nice length and with extensive use over a few months accompanied by an ADS i did manage to see 3 or 4mm of growth in my ‘fully packed’ state.
