Any abuse of anything is no good and too much of that could lead to a disease of being alone. I've never heard of an attacking bacteria that's caused by this. There is one strange example that has been mentioned as well that a man who does do it too much when he finally is with his lover can become impotent and fail to perform because of the psychological phenomenon that took place constantly substituting a real lover in real time for a mere thought of one. That is beyond me but maybe it is worth mentioning to you. Good luck. Live long and prosper.
