I caught my son 3 months ago in the bathroom getting his crotch licked by our pet dog, I have taken the dog to a family that will take better care of it because I can t trust my son anymore, I am afraid that my son will get sick though he s 15, and hasn t had sex other than getting his crotch licked by the dog, I am afraid he will get an STD or something from his actions, are there any diseases he could get from this?
