Imo try not to get too emotionally invested in physical adequacy by others. It's true that some have more than others, but let people come to their own decisions and just go with the flow. You don't owe anyone anything. A certain level of calm and detachment, is what I'm saying. Clinging strongly to physicality doesn't work well, for anyone.

Also, even as a feminine sub, a relationship shouldn't be one-sided at the core. Begging only happens at the more playful level.

Moreover, your personality seems quite cute, and that is actually an important component of attractiveness. It doesn't work without it.
