When someone is a size queen, it means that they have an intense preference for larger items, particularly with regards to sexual matters. A size queen might be referring to a preference for larger, longer or thicker body parts or sex toys, or they could be referring to a lack of interest in smaller, shorter or thinner objects. For example, if someone considered themselves a size queen, they would likely find more pleasure and comfort in being with a partner who has a larger penis than with someone who has a smaller one. This preference can apply to both sexes.
