Don't worry, that is ok.
So, yes, I did everything by myself, after I thoroughly informed myself about the procedure. I did not have the means of testing my donor for infectious diseases, therefore I placed great care on his medical record and we extensively discussed his health situation during the past six month; Everything worked out and we agreed on a date. I provided him with tupperware so that he could catch the sample and place it directly into the freezer. After I picked it up I cut it into smaller sized samples and stored them in my freezer. On the day of the procedure I prepared everything I needed and tried to keep everything clean. I then took a sample, placed it in a freezer bag and added some warm water to soften it. The thick brown liquid I transferred into an enema bag and applied it rectally. I then tried to keep it in as long as possible.
