I don't see any hard evidence it's a male, and he should be showing at least some signs by now. Maybe it's a stealth rooster... 'He' has the facial development of a hen though. The physical size doesn't really mean anything, males of many breeds are about the same size as females. Sometimes larger, sometimes smaller, but overall they stand more upright and seem larger because of it. The crest is a bit bigger but still well within the limits of a typical females' crest and could get larger without being typically male, too.
If you're friends with the person you got them from, maybe ask them. I think they gave you two hens. I had mine sexed by the breeder to get all females and she was wrong on 2 out of 10. Best wishes.
