The Silk large isn't a toy I would consider large, but it certainly isn't small either. It's appropriate for vaginal use, and I would say it's intermediate as far as using it for anal sex. The flared base makes it appropriate for being used in a harness, and this dildo is available separately or as part of the Tantus' Bend Over Intermediate Kit. It's safe for solo anal play as well since there is no danger of it getting "lost", but it's shape means it won't stay in on it's own like plugs do. It has enough density to be firm enough to be effective and has enough flexibility where there isn't as much of a chance of hurting your partner from going full force as a dildo with minimal give.

The Silk Large is very smooth and made of 100% silicone. It isn't at all realistic since it doesn't have any phallic like characteristics minus it's rudimentary shape. The shape is nice for those who don't want a dildo that looks like a rubber replica of a penis. It isn't textured which makes it good for less advanced or sensitive users. It is firm in that it holds its shape yet is soft and has enough give to where it won't injure your partner if you are rough or slip.

(Pardon the droplets of water in the photo; like most silicone/rubber dildos these are lint magnets and I wanted them dust bunny free for the picture.)

In the picture I show the Silk smooth with the Acute, which is another of Tantus' dildos (and pretty spiffy as well). It is maybe a tad larger than the average penis since the insertable length, according to the specs, is 6 3/4". Its girth is about on par with the average male; although, at the tip, it does flare a bit. I think the size is definitely sufficient, but I don't think I would say it is "large" as the name suggests. It would probably be a tad intimidating for beginners to anal play, but as far as vaginal play goes, I really don't think most people would have a problem with it unless they have any medical issues that would affect their ability to be penetrated.

Like most Tantus dildos, it has a flared base making it harness compatible as well as safe for anal play. It may be too big for smaller sized O-rings as far as harness use goes, but it should fit any medium sized one just fine. It's silicone and doesn't vibrate, so it's safe for travel, and you don't have to worry about someone else overhearing buzzing. Given that it's pretty obvious to anyone who knows what a sex toy is, this is definitely a dildo I wouldn't say is discreet enough to keep out in plain view of those you would rather have no knowledge of your sex life.

As far as performance goes, there is really nothing negative to say. It fits well in my harness and stays in place well. It's also well suited for solo play, and I personally think the flared base makes it easier to handle. If you wear your harness a bit lower given the girth of the base, you can also get more clitoral stimulation for the wearer. I haven't yet tried it for anal, so I can't comment on that at present, but given the flared base, it's safe for solo anal play as well as with the strap on, so I am sure I will get a chance test it out in the near future.

The Silk Large is easy to clean like most silicone dildos. You can wash it with antibacterial soap as well as popping in the dishwasher if you want to be SURE it's clean or just don't feel like hand washing it. I store mine with most of my other toys in a sparkly pink plastic tote with a towel at the bottom (high tech, I know lol). I have found that like most silicone/rubber dildos that no matter how clean that towel and no matter how tight that lid is, this toy is a dust magnet. I tend to wash it before and after use because of that. But, really, that's good practice anyway, so it's not much of a downside.

Like all silicone toys, do not use a silicone lube. If you do, you are out the price of this dildo because you will have to replace it. It works well with any of the water based lubes I've tried. Another way to stay ahead on the cleanliness (as well as good practice), is to put a condom on it. Switch condoms between uses and partners and whatnot as well.
