Is it safe for me to hang 2lb for 40 minutes a set? I was thinking about hanging 2hours a day.

What hanger?

If vac yes, if compression no.

I didn’t feel any real tension on my dick until I reached 7 lbs. i did four fifteen minute sets and built up to 13 lbs over three months until I lost my privacy.
