Maximus is a lube that works well in just about any situation, but is particularly suited to anything anal. I would assume that it works for vaginal sex as well, though we haven't tried it in that manner yet. That said, others on EF have said it worked without issue, and you could possibly thin it out with water, if necessary.

Another consideration is the ingredients, which are fairly standard for water based lubes. The main thing to watch out for are the paraben preservatives, which are under some criticism due to possibly being linked with breast cancer, though no actual correlation has yet been found. They can be an allergen in some cases though, so you may still want to research them first.

Here's the ingredients as well: Highly Purified Water, Propylene Glycol Cellulose Polymer, Di Sodium EDTA, Phenoxyethanol, Methyl Paraben, Butyl Paraben, Ethyl Paraben, Propyl Paraben.

The consistency of Maximus is probably it's best attribute. It's a very thick lube and so it stays where you want it to go. It has a very lumpy look to it, unlike the smooth water drop look of KY, but it doesn't have that lumpy texture when in use. Certainly looks cool as the bottle empties though!

It's amazingly smooth during use as well. It's a piece of cake to apply, and you should only have to do that once or twice!

There's virtually no smell, and it has that typical sharp lube taste. Not going to cause any problems if you accidentally lick some, but it's still something I would avoid. In addition, I believe that the ingredients are non-toxic, but you still shouldn't plan on dressing a sandwich with it anytime soon!

This bottle has performed like a champ. Most of the other reviews are accurate when they say it only requires one or two applications; it really does. Because the consistency is so thick, it goes where you put it, and stays there. Doesn't dry up for almost the entirety of your use, and it won't run halfway down your leg if think about moving, like Astroglide.

I have noticed something peculiar about the lube, however. Upon initially using it, I always get a really warm and tingling sensation. I don't know if it's any sort of allergic reaction or just a feature of the lube, but it never actually bothers me. Within two minutes, that's usually disappeared. That said, you may want to keep that in mind if it may affect you. (As mentioned in the comments, this may be a minor reaction to the parabens)

Also, the lube does feel really smooth, overall. It never really gets sticky, and washes off easily.

Another note on performance is that by being water based, it should work with virtually any material. I've personally used it with both rubber and silicone, entirely without issue. I've also yet to notice any staining on the bedsheets, which was a constant issue with Astroglide.

The packaging is also really great. The bottle's clear and could be fairly easily mistaken for something not sexually related. There's also a really awesome pump bottle...that I broke upon attempting to open. Being the fairly manly man I am, I've never opened a lotion bottle or anything of that nature, so I couldn't figure out where to twist open the lid from. Naturally, I brute forced it, which completely and totally broke the oh so awesome pump. Luckily, I had just retired my Astroglide bottle, so I stole that lid. Sadly, I'll have to wait until I've ordered more in the future to report back on pumping it up, so to speak.

Overall, this lube was well worth the purchase. If your planning on doing anything anal at all, get this. It lasts a lot longer than KY, and it literally blows Astroglide away. I had originally been using Astroglide for months because that was what was touted online at various sources as the defacto anal lube. Turns out it was the most impractical lube ever. It ran everywhere, needed to be applied constantly, and was pretty sticky too. Maximus was everything that I was originally told Astroglide was, which made me ecstatic!
