Something weird has been happening to me lately. When I'm getting more and more concentrated, I feel my breath slowing down. Sometimes, my brain stops producing thoughts for a while. Then, I start getting an erection! I'm not thinking about anything - no sexual fantasies or anything like that - it seems to be a purely physical reaction. Now, before I start zazen, I have to point him to the north, so he won't squeeze into my trouser leg! :shock: What's the deal? Has anyone experienced something like this?
