Cum

[Lodan]

Is it true that cum/jizz is mostly protein? how can that be? Wouldn't it be mostly, I'm not sure, water maybe?

I think this will explain it better http://menshealth.about.com/cs/stds/a/about_semen.htmter

Semen is water based, but when people say sperm is protein, it's the sort of molecule it is. It doesn't mean it's like protein in meat, it just means it like that.

The biggest single ingredient is water, of course.

Protein is a minority ingredient. See the Wikipedia article for a detailed analysis.
