It definitely works...
…along with hydration.
I have been following the regime described in here for a few years. I also pump with Bathmate X40.
It is not like you gush like crazy every time, but it’s definitely a big improvement. I find my orgasms are more powerful when I come more, period. My favorite orgasms ever always resulted in several, prolonged contractions.
Just as an example, the other day my girlfriend and I really went at it several times at night. So the next morning she said she was sore, but she gets turned on if she plays with herself with her head on the pillow while I kinda kneel and she gives me head. When I came, it was otherworldly, it was a ton of precum and then several long shots. Her face was a mess. :-) But she’s a champ, and laughed it off, and claimed she’d post it as a new profile pic on Facebook. :-)
I believe Lecithin and Pygmeum are the most important ones for me.
