Thanks Sabrina, and thanks to all of you who have contributed to this posting.  I just want to clear up a few questions and explain what I am going through.  First of all, I haven't started the chemo yet, but probably be experiencing that within the next few weeks. I had a cancerous tumor that was located in the upper ascending part of my colon, and this was removed in surgery that I had on July 20th.  The surgeon also removed the appendix, and a few lymph nodes as well.  He said the surgery went very well, and the rest of my organs, including liver and kidneys look fine.  Some of the lymph nodes did test positive.

I will be having a Medi-port implanted in my chest sometime next week, and will probably begin the therapy sometime soon after that.  It will be done on an outpatient basis, every two weeks, over a period of six months.  From what I have been told, I should be able to resume all normal activities even when this begins.  I am interested in hearing any experience with this.

there is no clinical reason that someone (male or female) can't have sex while undergoing treatment for cancer.  However, they probably won't feel like it.  They will be tired, nauseous, and in general feel like they have the flu or someother infection.  

In addition some may be worried about their appearance.  Lets face it, chemotherapy (in most instances) is taking a controlled does of poison.  it does not feel good.  Radiation therapy is similar - you are not going to feel well... and probably not be up to sex.

On the plus side, it might make you feel better - and provide an optimistic attitude and that could help you recover faster... and that HAS BEEN STUDIED - patients who feel better about themselves, groom themselves more and have more self image DO get better quicker and with fewer complications.

I say go for it.
