Parties arent the best way for you to get credits, when you re not the major hunk type (in your case, sorry).
You have to find a way to make a connection first. Just try to get to know guys, make the experience firstly more social than sexual. Let them know stuff you like, use your topics wisely.
I usually sing ahah, I have had guys tipping me for singing

they are the best. So stick to your strengths, after that go private.
Parties leave you too exposed, and make it difficult to make a connection other than a visual one. Which, if it isnt the most arousing, wont make customers tip.
Good luck
