The Feeldoe Slim is marketed as the first strapless strap-on and is intended for use with multiple partners. The idea is that while one partner is being penetrated with the penis shaped end, the "top" is being simultaneously penetrated and pleasured by the bulbed end, which is held in place by the vagina.

The Feeldoe is being marketed as being usable by both penetrative partners with vaginas and penises. The promise is that bulbed end can be inserted into the anus and be used to double penetrate a partner. I do not see this at all being feasible, to be honest, though admittedly I've never tried it. This toy is very heavy and is difficult to even hold in place with kegels in most positions. I also don't think the shaft is long enough to give any meaningful penetration.

I bought the Feeldoe as a potential solution to my gender dysphoria problems as a FTM trans person. Traditional strap-ons were enjoyable, but I often felt like I was missing out on a full range of stimulation, and was hoping that the extra "oomph" of the Feeldoe would help. Instead, because of the lack of versatility and stiff, clunky feel, I found it didn't do much for me at all. Of course, if you're a trans person with a vagina who does not like vaginal penetration this would not be a viable option for you in the first place.

The Feeldoe Slim is made from a very firm silicone. The firmness of the Feeldoe was actually a big turn-off for me. It does not feel realistic at all, which is obviously an important factor for someone grappling with gender dysphoria. Not only that, but my partner found it to be so firm that it was actually kind of uncomfortable to be penetrated by it.

Near the base of the Feeldoe are three pronounced ribs for stimulating the clitoris during use. I don't know if the Feeldoe fit me right because I didn't seem to get any stimulation from these, but I suppose if it did hit the right spot, the ridges would feel pretty nice.

Even though this isn't unusual for silicone toys, the Feeldoe attracts dirt and lint to an almost unheard of degree. It will literally pick up lint off the bed sheets even while you're using it. It definitely needs to be washed both before and after use, even if it's stored in its original packaging.

There is a seam running through the center of the toy, which is to be expected, but luckily it's not pronounced or sharp at all.

The Feeldoe Slim has a long, slender, penis shape, to penetrate your partner. There is something of a "head", but it is not very pronounced. This side tapers down into a thicker base. In the back of this base there is a hole to hold a small bullet vibrator, which is included. Sticking up out of the base is a bulb, which is meant to be stuck into the penetrating partner.

The taper of the head and shaft are all very smooth and gradual. It is wider at the top than closer to the base, which allows for some flexibility when inserting into your partner. The Slim truly is slim; with a 1-3/8" diameter, it definitely seems to be at least a bit thinner than the average penis. As such, even a partner with only very limited anal experience should be able to easily take this toy.

One of the biggest problems with the Feeldoe is not inserting it into your partner, but inserting it into yourself. While the bulbed-end is ultimately not terribly wide (wider than the end you insert into your partner, however) it is very blunt, so there's no real way to ease into it. A lot of my friends with vaginas had problems with this toy--including ones that are not trans--so if you're a trans person with a vagina who has even a slight amount of bottom dysphoria like myself, the Feeldoe might be difficult or even impossible for you to use. It definitely intimidated me before my first couple of uses.

The most distinctive feature of the Feeldoe, of course, is that it's supposed to be able to be used for penetrating a partner without a harness. However, the Feeldoe Slim weighs in at a whopping pound, so unless you have super-powered kegels, I don't see this being the case, except in a limited number of positions. Some of my friends have told me they use the Feeldoe in conjunction with a harness or while wearing underwear. I've never tried it, but for the money you spend to get a "strapless strap-on", this seems to defeat the purpose.

The other problem I found was that the included vibrator has only one speed and not nearly powerful enough to resonate through the thick silicone. Luckily, the vibrator can easily be switched out or replaced if it is broken. If you enjoy the vibrating sensation and can actually find a position where the Feeldoe works, at least you can be assured that it will be in your toy box for a very, very long time.

The silicone is ideal for use with multiple partners because it can be sterilized between uses by placing it in boiling water for ten minutes (though, in situations with more than 2 people, you should still wear a condom).

Of course, silicone-based lubricants should be avoided because they will damage the integrity of the material.

The only position in which this toy has worked for my partner and I has been with him riding me, and even then it has a tendency to slip out. We have to fuss so much with it that it's almost not worth it. The vast majority of the time we still opt for the traditional dildo and harness, so the Feeldoe stays neglected.

It also definitely didn't help with my dysphoria at all. I don't know why I thought that a bright blue silicone dildo would give me a "realistic" feeling, but I guess I was so desperate for a solution to our stimulation problems that I was willing to try anything. Since I've bought the Feeldoe Slim, there is a new line of toys called the Realdoe that are made to be highly realistic. I've not felt one yet, but I have seen it and it does look very impressive. However, for the price point of the Feeldoe/Realdoe, I don't think it's a worthwhile investment. It hasn't worked for us like it was intended to, that's for sure.
