I find it easy to balance function and fact in my reviews. I will say if a toy is better for internal or external, etc, how I found it most useful in my usage (On one review, I noticed particular movement patterns I found useful with a clitoral toy) but I try to avoid erotic description.
I will attempt to clarify this through example.
Normal description: I find this toy to be amazing for G-spot stimulation, though it is probably best for people who already know what they like and how to find their G-spot as opposed to those who are new to G-spot play. This toy can be used for clitoral stimulation as well, and the broad and deep vibrations will make it easy to target your clitoris, despite not having the pinpoint control of a bullet.
Erotic Description: Oh god, I just can't stop fucking myself with this toy. I love how it pounds into my G spot over and over again! it makes me squirt like CRAZY. I just get all lubed up and go to town! I take it in the shower and shove it into my snatch, and its so strong, you can even rub your clit with it. I just can't stop CUMMING back to this toy, hehe.
Too Much Information Description: I got this toy in the mail, and I just couldn't wait for everyone to leave the house! With hubby at work, and the 2 year old FINALLY put to bed, I dove into bed and got all set up- only to be interrupted by a phone call from my boss!...
The last two are exaggerated, but I have seen all of these traits in reviews. one 'TMI' review even mentioned the girl lying to her mother about what she got in the mail, insisting it was a sweater, and then hiding the hole in the sweater she happened to be wearing. While it may be a cute touch to me, seeing as the reviewer was being erotic just a few sentences before, somehow I did not want to think of her talking to her mom and having to hide things from her- It makes me feel like the reviewer is underage when they mention (constantly, in reviews) dodging parents and family. I live with family too, but you know, they get over it. I am of age and they will deal with my choices.
About being super erotic, I just can only handle so many "juicy pussy"s and "throbbing clit" phrases in one day, and it gets annoying when the review is like "oh yeah it vibrates and takes some batteries NOW LETS GET TO THE SEX". That tells me nothing. I don't mind hearing "It works best with G spot stimulation and can also be used on the clit- the sleeves provided can provide more texture for clitoral stimulation" or even "It feels especially nice here/if you use it in this way" I often use these phrases and examples in my reviews since as a reviewer I feel it is my duty to represent the toy I myself am reviewing- some toys can be hard to figure out, or people will look for new ways to use them, as well, some toys aren't good for their intended purpose, but are excellent for other purposes, or some vibrators or toys can be dual purpose. Due to this I think some info is necessary, but when you get into "I thrust it into my sopping wet vagina" land, you've crossed the line for me, and I usually think it's not useful to me unless there are a LOT of facts and the erotica is ONLY in the experience section.
