How can I gain more respect from dragons?

So recently, i joined this group of dragons to go on adventures with as I'm kinda in a need for some money. Overall, they've been alright so far. I get along greatly with a couple of them. It's yhe others that are the main issue. Well, one I should say.

The others and I, we just really haven't made that spark of friendship, we're sorta acquaintances at most. But this one dragoness seems so aggressive towards me. Anytime she's "playful", I'm nearly choked or squished/pinned unconscious, to the point others have to step in to get her off me. She claims she's 'testing me'.

Now, I understand most Dragons see roughness/aggression as respective behavior. Is there anyway I can do anything around here to gain her respect? I'm kinda getting sick of her just shouldering me and making a mock: "Oh, sorry 'bud'." She acts like we're so close.

As only half dragon, it's hard for me to try and get the same respect full dragon's do.
