Personally, I think Maximus is a great all-around lube, thanks to its thickness and quality. Water-based lubes will absorb if you're doing a lengthy handjob, so if reapplication is an issue, you'd want to keep that in mind.

I have never enjoyed giving a handjob using silicone lubricant; it makes me feel really greasy.

My one guy friend really likes boy butter and buys the industrial-sized tubs of it.

Whatever I don't want in my va jj. He will use my left overs and isn't picky.

I just tried out Bodyglide the other night and it's a fantastic lubricant. I hear ID velvet is good quality too, along the lines of bodyglide.

I remember the days when my husband would come out of the bathroom and I'd go in afterwards and notice all my bath & body lotion bottles were half empty- his crotch would smell like b&bw for hours. lol.

Any water-based lube will dry out pretty fast during masturbation - there's just too much area exposed to the air. Maximus is pretty good, but users will still need to keep some water handy (perhaps a small spritzer bottle, so you don't get too much on and wash off the lube).
Maximus is a bit bitter as well, so if there's a likelihood of the handjob becoming something else it might be good to avoid.

Oil lubes work quite well since they don't dry out, Boy Butter is about the best out there as it cleans up easily. The downside there is that it's better to take it off of anything that will go in a vagina.

I've tried out some suggested "easy to find in the home" substitutes, and body lotions absorb too fast (and can irritate the mucous membranes), and coconut oil doesn't stick around very long either.

We usually use KY, and it works pretty well.

My b/f uses Maximus, we use this for just about everything. No messy stickiness and doesn't get all over everything. If need be he just adds more.

An interesting alternative lube for hand jobs is Boy Butter. It is a plant oil (not petroleum) based lube so it lasts longer than a lot of water-based lubes. I also have not had a problem using it with any of my silicone toys. Definitely worth a look.

Stroke 29 is defenetely an excellent choice. Google it up. Haven't tried it with toys yet.

Thanks to Average Joe's recommendations, as of about 10 hours ago... Eros Original Bodyglide is my new favorite lube for handjobs!
