There is no such thing as a normal penis size. The size of your penis depends on your genes, just like the size of your hands, feet, and eye color. Keep in mind, penis size has nothing to do with manliness or sexual ability.
T-Shirt Considerations. Words and logos on T-shirts can be protected with the USPTO, but the overall design of the T-shirt is actually protected by copyright law. As soon as the T-shirt is fixed in a tangible medium, any creative and original aspects of the shirt are protected by copyright law.
Copyright Ownership and Rights. Sometimes, someone other than the creator of a work owns the copyright. The creator of a copyrighted work does not always own the copyright. In some cases other persons or entities own the copyright. There are also rules governing copyright ownership when two or more people create the work. Finally, copyright owners can assign rights to the copyright to others, particularly for the purpose of marketing the protected work.
