I have a hard time with the foreskin. Dylan O'Brien is about as american and white as you can get. (not insinuating he's racist, but the odds of him being circumcised are extremely high)
I agree 100% with this assessment and so far there is only indirect evidence regarding foreskin, or lack of it, on Dylan O'. I am uploading files (that I have posted previously in other relevant threads). They both show dick imprints and they are both ostensibly authentic pics. One is a cap from a show in which DoB is in an excited state. There is a head outline that suggests he is cut or that his glans emerges readily when he is hard. The other shows him soft, with what looks like an imprint of a bare glans - down and to his right a bit. Now ..... if Dylan would only give us conclusive proof one way or the other.
