Can Someone sex my BGJD?

[diggler81]

I have this BGJD with a EBJD which I think is a male and they have been acting like they r getting ready to mate but I am not sure if the BGJD is male or female any help would be great. Sorry for bad pics could not find my camera had to use phone.

the bgjd looks male but will need better pic of side of face if you can get it (would sex him visually just like you would a regular jack since they will look the same), also ebjd have to be vented to know their sex for sure
