The SinFive Emigi is a "sexerciser" toy made to strengthen the PC (a.k.a sex) muscle. Go ahead and do some of your own research to learn how this muscle is essential for sex, childbirth, and orgasm.

How you use this toy is going to depend on how comfortable you find it. This toy is on the smaller side compared with other "sexercisers". That means it is less intimidating, but for some ladies, it's not going to stay 100% inside all the time. I find it interesting to notice when this toy pops out. Usually I wear it around the house while I'm getting ready in the morning. I find that when I'm relaxed and just going about my business, it stays in fine. However, when I start to rush or get stressed about something (even if it's a minor thing that I didn't think was stressing me out), the toy starts to pop out. I'm going to continue using this toy, and see if I can train myself to stay more calm and therefore keep it in.

The other factor in deciding use for this toy is whether or not you find the idea of wearing it out in public thrilling. It is an utterly discreet toy, so really it would be your secret if you had it in while doing errands, or going about your daily business. I would like to work up to wearing it for extended periods, but have found that I end up taking it out after half an hour or so unless I'm sitting down.

The SinFive is smooth and velvety in texture, but not squishy. For me, it's easy to slip inside with just a little water or my own fluids for lubrication.

I find it interesting how sensually the toy changes from being inside me. Before insertion, the toy is room temperature, and smells mildly of the material it is made of. After taking it out again, it is very warm from my own body heat. Often it also has a little vaginal discharge, and it smells like my vagina. I love getting this reminder of the visceral reality inside my own body.

This toy is shaped like a smooth peanut divided in half with two different colours. I got the black and white kind, and am appreciative of the colours because sometimes I'm just not into the whole baby pink-to-red colour spectrum. The black and white is much more mod.

It's got a handy little pull string that was psychologically calming at first, but really, probably not necessary.

Size-wise, this one is small compared with other "sexercisers". Maybe it's on the small side for me, but I find it quite elegant.

I find the act of inserting the SinFive Emigi to be stimulating to my PC muscle. I can feel them twitch around as they get used to the new object. As I move around, the little balls inside the toy shift and vibrate lightly which further stimulate the muscle.

I get a totally different and stronger sensation when the toy half slips out, suddenly coming into contact with my shallow vaginal nerves. This actually feels really nice. Maybe someday the pleasure of this feeling will overcome my anxiety that the toy will slip out entirely, and I will be able to walk around calmly with it in this position.

There's a great little instruction pamphlet that comes with the SinFive Emigi. It is good practice to wash the toy before and after each use with warm water and some gentle soap. I also dry the toy before storing it in a little box I found.

The packaging is simple and minimal. It comes in a clear plastic case with an information pamphlet folded up that also acts as a label for the product.
