That is a lot of good information, thank you.
I think this might also explain why the big jocks do not usually seem to be very smart.
So far I see no good side effects, and depression being a very bad side effect, I think it is better to leave a guys testicles attached.
So it sounds like the pituitary is the mysterious link that completes the loop. Without the penis, his testicles would still trigger the pituitary, and his sex drive, there just wouldn't be any way for him to get off. I think that guy would be so much fun. Would there be bad side effects if his penis is removed? Hopefully not.
I sometimes wonder if I have a mental disorder because of my desires, and now I wonder if I may have dis-morphism.
