So you're just trying to get laid? Are you asking for IRL or for apps?
For short term relationships guys look for assets, how easy you are, and how experienced you're likely to be. Think Catherine from Great Gatsby. Being chubby is not necessarily a bad thing if it ends up in the right places.
Long term will be much harder since it's more controlled by guys' protective instincts which trigger around child-like features and slender women who seem more vulnerable.
