Naked Men - an illustrated guide

Of course, one of the advantages of homosexuality is that you should already have a working knowledge of your prospective partner's body - no need for a diagram to tell you what the various parts do. Having said that, if you are one of those fortunate souls lucky enough to look this good naked, you should bear in mind that not all male specimens are similarly endowed. (We just don't want you to set yourself up for a disappointment).
