Colour scheme

I get quite a few funny questions, but I think my favourite so far has been:

"Is the colour of the sperm of an HIV-infected person different from normal? What is the colour of the sperm that comes out of the penis of an HIV sufferer? Is the semen of an HIV-sufferer also different from a normal person?"

Another questioner was also worried about colour:

"Will a person who has caught HIV have a penis with a different colour? What are the physical characteristics that can be seen on the penis of someone infected by HIV?"

I'll leave you to guess at my answers, but my tongue was firmly in my cheek!
