I would'nt exactly describe him as 'sexy' but he does seem like someone who would have a dick.
Myself and very many people beg to differ with your rather personal analysis, of him not being sexy. Especially when he is on that competitive winning streak.
Attraction and attractiveness are universally accepted traits, for men mainly based on facial symmetry, facial hair, bright sparkly eyes, strength yet tenderness and a caring nature, a V shaped torso and a masculine aggressive streak, all traits he has by the bucketload. He is something much more than an idealised airbrushed image of a twink, that recently some media pressure would have us believe is the best.
Regardless of the size, his dick has been described when soft as of average length, rather thick, uncut, dresses to the left and goes commando most of the time
