I had a fuckbuddy like that years ago. He had been given hormones as a child, because his father thought he was exhibiting "homosexual tendencies," and found an unscrupulous doctor to "treat" this. This made sort of a mess out of him, as in later life his body did not properly produce testosterone, he suffered from depression that is often associated with hormonal imbalance, and despite all he was still gay. However, presumably as a consequence of the early hormonal treatment, he had a rather large cock, but comparatively tiny balls about the size of grapes.
