I would say Toyfluid is effective enough for simple penis-in-vagina intercourse. A quarter sized amount is applied to the vaginal entrance and/or penis before penetration, and that amount is enough to ease discomfort upon first inserting and reduce the grabby-pull effect of penis going in vagina. However, it's not a lubricant I like using for clitoral play or massaging. It dries up too quickly for that and isn't as slick and friction-reducing as my favorite Aqua. So I've really limited the use of this to kegel ball insertion or to ease discomfort of sex at the beginning.
If you're someone who requires lubrication more than just once right before penetration, I would recommend going with Aqua, Liquid Silk or Maxmius over Toyfluid. It's comes in close to Aqua, but just isn't quite as lubricating as those are. If I weren't able to produce plenty my own natural lubrication, I would not prefer this over any of those above choices. This is just a runny, thin lubricant that does the trick, but isn't much more than that.
For those of us who like clitoral massaging, this is not going to last as long as needed without several applications. However, it's a really good lubricant for someone who doesn't require much at all or for someone who only needs a dab upon insertion and only that. It's a good choice for daily kegel ball insertion, but I'm really far more fond of Aqua, and just can't put my finger on exactly why I preferred it over this.
As for anal penetration, you could use Toyfluid, but I do not recommend it. I've never experienced any kind of anal penetration, so I can't be certain, but I would think this would be too thin and runny for proper lubrication. Aqua, Maximus and Liquid silk are a little "gloopier," so I would have to advise against this for anal penetration since you have lubricants specifically made for that purpose, as well as other water-based lubricants that would do a little better for lubricating the hiney.
As for a handjob, neither me nor my partner thought this was a good lubricant for that. If you're stroking slow and light and not for anymore than a few minutes, it'll do the trick. But for vigorous thrusting away with a hand, this absorbs like a towel does water. It does not reduce the friction enough for a decent chicken chokin'.
Keep in mind this is water-based, so it's compatible with all toy materials, it's latex safe and won't damage condoms.

Now, let's do a little comparison to sort of dig down deep and find why this just doesn't do it for me like the fabulous Aqua, Liquid Silk or Maximus.
Above we have the contestants in the lubricant comparison thingy. From the left, we have Aqua, Maximus, Liquid Silk and then last and definitely least, Toyfluid.
Take a look at the photo below. I've put a drop of each lubricant directly on the counter in front of their bottles. It took me forever to get a photo that didn't capture the blasted glare off the counter top, so hopefully you can see this. The white drop is Liquid Silk, and the rest are clear, but you can see who is who by looking at the bottles. Toyfluid is the last drop on the right, beside it is Aqua, then Maximus, then Liquid Silk.
I'm not sure how noticeable this is just by looking up there, but Liquid Silk and Maxmius, when squeezed from their bottles, leave a nice, plump, gel-like ball. They do not move or run. Then Aqua and Toyfluid, well they both tend to begin spreading and are more of a flat liquid when dispensed onto this hard surface. They do not bubble up and stay right in their plump little round ball. Instead, they flatten out. You can see that Toyfluid is pretty much just flat as a pancake and Aqua holds a bit of a form.
And here they all are on my finger tips. I wanted to have decent photographs showing each lubricant I'm comparing, so we have us a variety here. I just hope I don't overwhelm you. In the picture above you see the finger tip with a white glob is my own natural lubricant. Kidding! Kidding! Sorry, I couldn't resist. Okay, you see my bird finger there? The white glob on it is not my natural lubricant, it's Liquid Silk silly! Beside the bird finger is Aqua and on my pinky is Toyfluid. A big thumbs down for Toyfluid! I love Aqua, even though it's thin. It still does such a wonderful job, but Toyfluid is just thin, watery and doesn't do a fabulous job. You can see that Toyfluid is the runniest as it's nearly dripping plum off my pinky in that picture. Aqua has a tiny, tiny bit of a gel-like viscosity to it, so it has more of a form rather than being drippy, runny, watery.
And here we are on my arm. The white, again, is Liquid Silk, beside it is Maximus, beside Maxmimus is Aqua and the last one on the left is Toyfluid.
When put to the test yet one more time, Toyfluid is still the runniest out of the four. We have Liquid Silk in white on the far right, then Maximus sitting there all proud, holding his nice gel-like shape so wonderfully, then Toyfluid failing miserably, and last on the far left is Aqua who can't decide what he's going to do, but at least isn't running for dear life like Toyfluid.
First of all, when I first used Aqua, the super slippery, slick feeling was slightly similar to a thin silicone lubricant. In fact, I even prefer Aqua over the entire Pink line of lubricants. Pink has nothing on Aqua, and sadly, neither does this. This has no super slick anything. It's not going to even come close to reminding you of the good ol' silicone days.
