How often is too often?

I'm an older guy with BPH, enlarged prostate, and recently, have found the Aneros very effective. The sessions are extremely pleasurable with have no problem achieving most of the great experiences talked about  and sort after here. Probably BPH actually helps make HFOs easy in this case.

Along with some Kegle exercises, the Aneros use over the last couple of months has definitely also helped reduce the trips at night to the bathroom. Too bad no studies have been done to show how well these work for BPH.  I suppose it's just not a money maker for the medical industry so no studies means it doesn't get any support as being useful.

My question for those dealing with a similar issue is - how often do you session with Aneros? Like anything I'm sure it can be over done but what is the norm would be helpful info. I'd like to get feedback on generally what others older guys use frequency is?
