Most of what I have found on RE describes "situational" RE. (i. e., climax is possible via masturbation, but not with a partner.)
What do you do when the situation makes no difference?
For me achieving climax can require up to 3 hours of stimulation whether I am with a partner or alone. This isn't anything new, it's been like that for as long as I can remember. However, this year it finally reached the point where I *have* to do something. I have developed RSI's of the wrist and shoulder from masturbation. (How sad is that?)
The few mentions I have seen of non-psychological / non-pharmaceutical causation all relate to neurological damage. If this is the case, can anything even be done?
