You are acually talking about Negro Top Delicia, his was cut in a scene by braces of a girl during the blowjob. Unfortunately accident happen some are even worst, I have witness two times where the dick of the guy got broken during the scene, usually it is from a careless actress or the actress is just overwhelm with all happening or just by fatigue.
It once happened to me that I almost lost my eye in a 2on2 scene where the girl's big heel went straight to my face, fortunately I quick to see what was coming and ended up with just a cup on the nose and skin below my eye.
Going back to him, I beleive is a good actor with a lot of great potentials and the most important thing, very humble and a great team member, which is very important when working with guys in a group, as you probably know about the EGO problem with male porn actors. I have been training him to adapt to the Gonzo style and I think he is learning very fast. Brazil is full of wood problem guys, I have one time took 2 hours to finish just a 5 minute part because of one actor wood problem. He rarely has the problem and I desaparetly need such actors because I rent the shootig location on the daily basis.
What can be done :
1) Film on the other side (have his dick's right side which has not a scar face the camera) which I did in the first scene with him but became very unnatural to the rest of the crew, especially with positioning. Check the attached pictures below
2) Get used to the way his dick looks and concetrate more on his fucking skills. He is a very good fast and hard fucker when paired with the right girl ( I mean the girls who let a big dick pound hard their ass).
