1, I preferred the bit where you told me to post on other topics if this didn't interest me 
2. By you people it's people who request this - I'm just waiting for 'a toggle ' to be suggested.
We seem to be getting this thread in a different guise every week with generally the same proponents.
3, I've always wondered about those in a non-sexual, deep and meaningful relationship - do they still crack one off in the bathroom when the other half is out?
1. I'm still a bit sick and muddled so I had you mixed up with the post I mention below or above - whichever way it is. I changed it because its tone seemed a bit unpleasent which I felt was unwarranted given your post. I can reapply it more politely if you'd like.
2. It is not as much a request for a toggle as I see but a request for an option that continues the relationship without trigger the sexual content, albeit one worded incredibly poorly. Basically, a "I feel this is a bad time" or "I want to get to you first." kind of case.
3. Some do: they may be a person with a lowered to non-existent sexual drive who have no interest in sex but who still masturbate though it is not always due to sexual interest or thoughts and sometimes caused by stimulation.
To give a reason that is untied to sexual interest or drive: In the case of sperm build-up that was previously mentioned and from what I can understand based on further reading, the male body tend to never cease to produce semen which can lead to a need for the body to divest itself of it which the body can do by making itself overly sensitive to stimulance like a breeze or a blanket thereby either leading to quick release or slowly dripping it out little by little. This can apparently be the cause of wet dreams according to some.
