I bought a cylinder and a seal a few days ago (saw it as a cheap alternative to [words=https://officialhydromaxpump.com/?uid=6&oid=2&affid=98]bath mate[/words]) - I have been pumping at around 1-3hg. However no matter what - if i go in erect or semi - i come out flaccid. It's really annoying, I see no expansion at all from pumping. I don't know what to do and i'm getting quite frustrated from it all. I have ordered something to allow me to pump with water so I will see if this makes a difference.
