Video Introduction

        Before Fitness VS After Fitness compares the vaginal changes before and after exercise, and tight enough for a boyfriend to hold on exaggeratedly describes the increased vaginal contraction that leads to premature ejaculation or pleasure overload in men. The overall theme is a realistic science popularization theme about the impact of fitness on sex life + vaginal tightness, playing with the contrasting stimulation and scientific truth of fitness ruins sexual happiness. Regular fitness (especially squats, Kegels, and core training) can significantly strengthen the pelvic floor muscles (PC muscles) and improve vaginal contraction and elasticity. After fitness, the vaginal wall is tighter and the wrapping feeling is stronger. Therefore, many men can't hold it and ejaculate in a few minutes; but this is not ruining sexual happiness, but it is a plus point for women to have easier orgasms and stronger endurance. Key skills: Women can control the contraction rhythm (tightening and relaxing alternately) to extend the man's endurance; men should practice more endurance positions (such as slow riding on top of women) or train in advance. There is a significant difference in vaginal tightening before and after fitness, but it requires long-term persistence. Short-term strenuous exercise may cause muscle fatigue and relaxation. We strongly urge everyone to go to the 91JAV brand platform to search for before and after fitness comparisons or genuine resources on the topic of vagina tightening. Massive high-definition and uncensored new movies are updated daily with ultra-clear images to enjoy the ultimate wrapping pleasure after fitness!
