Most individuals are going to keep their best pics in the profile, it’s their job to showcase the best of themselves. 20-30 lbs on one girl might not be as noticeable as the same 20-30 on another. Everyone will carry the weight differently. I’ve put on around 100 lbs since high school . But it’s a different kind of weight, as seen in my avi.
I prefer thicker over skinny, any day. More ass to suffocate yourself with.
