Multiple Os

Very few studies have considered segmenting individuals by orgasm threshold. In one study, Umit Sayin uniquely categorized females by how they responded to a vibrator that vibrates at different frequencies:

GROUP-A (Moon women): Women who can achieve clitoral orgasms by means of very low stimulation frequency (25-40 Hz). They can even attain orgasms by very minute vibrations.

GROUP-B (Sun women): They can attain clitoral orgasms by higher frequencies such as 40-60 Hz. They can have orgasms by the vibes sold in the sex shops.

GROUP-C (Earth women): They can attain clitoral orgasms by 50-80 Hz moderate orgasms. They may be aroused by lower frequency vibrators. Some of these women can have good satisfaction by the vibrators sold in the sex shops.

GROUP-D (Sky women): They can be stimulated and attain orgasms by a wider range of stimulation frequencies (40-100 Hz). In the beginning frequencies which are at the range of 50-60 Hz can induce orgasms in these women. But a kind of desensitization may develop after a while and some of them may need massage vibrators and more powerful vibrators. In the long term they may need 70-100 Hz vibrators to be aroused and to have an orgasm.

GROUP-E (Venus Women): They need very powerful vibrations such as massage vibrators, which are around 80-100 Hz. And they may need to increase the intensity after a while.

It’s important to note that some individuals may respond differently to different vibrators with different motors vibrating at the same frequencies. Individuals may fall into different categorizes depending on the type of orgasm too. It also does not account for pressure used. While it has some drawbacks, it’s very effective way to understand how individuals respond differently to different vibrators on the market.
