Re: Does being receptive of Anal sex cause impotence in men?

One of just many problems that can occur. Impotence is the inability to 
maintain an erection. It is thought to be more a higher motor neuron 
issue, ie cerebral cortex. As an aside - our most important 'sex organ' is 
our mind. I imagine you are asking about erectile dysfunction. This term 
covers more of the physiology and anatomy. However, again, one must 
remember that sex/intimacy is much more than genitals. In terms of design, 
the anal sphincter system was not intended for objects entering. The 
wiring is all backwards. Thus, one can expect damage to occur, sometimes 
immediate, others as more of a repetitive damage pattern. Anatomically, 
there are two doorways. The internal circular door is controlled by the 
involuntary nervous system - it runs on automatic. When a bowel movement 
enters the rectum pressure is exerted against this 'door'. The door 
gradually opens while sending a message to you - 'time to find a 
bathroom'. The outer door is under conscious control - you release it at 
the appropriate time and place. When I do a digital rectal exam on a man I 
explain all of this to them. I also point out that doing a 'quick exam' 
causes a tremendous amount of pain as it violates the rule of function. 

Another big problem is rectal incontinence. After damage has occured, 
these doors start to lose their integrity both anatomically and 
neurologically. The wiring and the structure become damaged and 
nonfunctional. I am not sure what can be done at this time. Most surgical 
procedures where a rectum is created from bowel work best when the anal 
sphincter system is intact. 

A point I alluded to earlier covers the broader psychological aspects. 
One's sense of 'manhood' may be damaged in such an experience leading to 
conflicts inside over a sense of who they are and their 'value' as a 
person. Cases involving men raped in prison settings illustrate this most 
clearly. 

Finally a broad range of infectious diseases - from the more mundane VD to 
the exotic 'tropical bowel' or 'gay bowel syndrome' are the outcome many 
times. Along with this comes altered immune status which can culminate in 
AIDS, with HIV being implicated as the causative organism. 

Hopefully this helps.
