Sorry, guy, but I’ll have to disagree. The stuff’s nasty and I don’t like using petroleum products on my skin if I can possibly avoid it.
There are lots of guys who’ll agree with you, though.
Personally I like jojoba oil. It’s light and washes off really easily and is good for the skin (hair and fingernails too). If I find myslef jelqing in the shower, I just use a little Dr. Bronner’s Castille soap, which is essentially olive oil. You don’t need much, and when it washes away it’s cheap enough so I don’t worry about using a little more.
Ditto on both of those. Good choices Mr. H :-)
