Wow, some of you are just way too homophobic! (not all of you)
IMHO.
All you have to do is draw it, it's like looking at anything else and sketching it. Just ignore the fact that that organ has anything to do with sex. You only have to sketch it, it's not as if you have to put it in you mouth.
I have three friends (men) who have had to do this type of thing for the past year, they don't care because to them it's just another image.
