We tease my older (neutered male) Yorkie about being gay because he likes to hump both puppies (a male and a female). He will also "clean" my male puppies parts (both puppies are now fixed). It is about who is in charge and also playing to some extent. I would not be concerned about the behavior. The best thing you can do is distract. Offer a toy and try to get them to play instead of humping. My older male just gets so excited when they are playing that he starts humping the puppies. The female puppy is in charge so she doesn't let the older dog do this any more. However the two males are pretty equal and so my puppy does not really care if the older dog humps him. It is normal behavior. No harm is being done, although I understand where you are coming from about it being gross. I just grab a toy and offer to play with my older male dog as he loves to play with toys. My older dog had not had puppies for the first several months I had him and he never humped anything. The puppies came along and after he was afraid of them for the first couple weeks he started humping them. Girl puppy got tired of it quickly and let him know that she was not going to tolerate it, but the male puppy just ignores the behavior.
