There's a huge unadressed problem in the MMO community (multiple male orgasms). The lack of definition. People talk about completely different things, thinking they are on the same page. Which leads to so much confusion and frustration.
So let's shed some light and talk about the types of orgasms and the different methods that get you there.
Work in Progress - this is how the encyclopedia and explanation of terms will be embedded.
1a) achieved through normal penis stimulation
1b) active HFWO (hands free wet orgasm), achieved usually through high arousal combined with intense physical anal stimulation
1c) passive HFWO hands free ejaculation, like 1b but through muscle contractions and maybe an aneros toy. Common to happen to Mindgasmers who still focus on the penile sensations subconsciously. (related to type 3a)
(There are probably more techniques, we'll stick to the ones relevant for us.
Like female ejaculation, men can squirt too. The expelled fluid is not semen, but likely a mix of diluted urine and pre-cum. The amount of fluid can be significant - up to 1 litre. The fluid is expelled in short waves of contractions. There is no refractory period.
It is reached through intense manual/toy stimulation or vibrating massagers directly on the prostate, usually combined with extreme pushing out of the whole lower region.
3 Dry Orgasm/Mindgasm
This is what we are here for. These orgasms don't need manual stimulation and are true "hands-free". There is no ejaculation connected to the peaks, but a constant trickle of pre-cum is common. Their intensity is basically limitless - as is their frequency. You can have countless of these in sessions that can extend several hours. Even the pauses in between the peaks are usually spent in a state of bliss. The average intensity level can keep rising throughout the session and at some point, even the pauses are spent in a state of bliss and the peaks can be labelled "Super-O"s.
a) Aneros Orgasms: Reached through contractions in combination with a prostate massager.
b) A-less (for "Aneros-less") Orgasm: Reached only through contractions, without a toy.
c) Mindgasm No toys. No contractions. Reached only through a combination of relaxation, focus and mental techniques taught in lessons 4, 6 and 7.
So there's basically 7 different kinds of orgasms, each reached through different techniques. But they are all thrown together under terms like Super-O and Prostate Orgasm. So if you browse subreddits for information or ask a question: Always make sure you are talking about the same thing. Because even the best method will fail, if you are using it in the wrong context.
