Two average vaginae. One is “healthy,” the other is pressured by body fat. Which feels tighter?
The choices are yours, and yours alone! /Olmec
My reasoning is this: A vagina could and likely would feel more “tight” with weight loss. After losing 100+ pounds it may feel tighter because the woman’s overall health would have improved. Better circulation would improve responsiveness and functionality. But would it feel tighter than when extra fat was pressuring the vagina? No clue.
The condition of a woman’s pelvic floor is (mostly) going to determine how “tight” or “loose” she is.
Most people who are 100+ pounds overweight aren’t going to have many parts or systems that are in best working order. I doubt most obese woman, or men for that matter, have very “healthy” pelvic floors. Losing that much weight is going to improve just about all one’s functions, including sexual performance.
Really, it’s an odd question with too many variables to answer.
