Well tritium, I checked out the link that you posted there and it turns out that I have pretty much the same 'conditions' as are shown there. I too was concerned with the bumps on the base of the penis, so I actually went to an std clinic and had it checked out. I was told within a matter of seconds that it was nothing to worry about as the bumps are just oild glands and that all males have them in varying degrees.
In terms of girls "discovering" this, chances are that if its a one night stand, the girl knows enough about a man's member that she will probably have seen this sort of thing before. If you are with a girl for a long time (a virgin even), the two of you probably have enough trust in eachother to not hold anything against eachother. I have yet to encounter a problem with this 'condition' with any girl I've ever been with, so I will tell you not to worry too much about it.
I'd also like to say good job to you for coming forth and discussing this on here. It kinda helped me again too
