I'd be more squeamish about drawing said penis. Not because i'm disturbed by people's naughty places, but more that i would end up trying a little too hard to make it look right.
For instance: Would he have a pickle-wang? Would said pickle wang look like an elongated green sock? Would said wang be more-human like? Does pickle-man shave his manly-pickle crotch like a little girl? The possibilities are endless.
