Welcome to my page celebrating the sexiness of diversity, individuality, and contrast. I'm Brad Logan, a tall muscle-bear-daddy-type who loves interacting with and filming men of all different backgrounds, ethnicities, and body types mixing it up together whether one-on-one or in group situations and sharing them with you.. There are so many different kinds of sexy men in the world and Alpha Spectrum aims to celebrate all of them through videos and sex-positive events.
