Help my buns are not so perky

What am I to do, just last week I made a short video of myself in the shower with a dildo stuck to the glass door and penetrated my pussy with the camera recording my whims of thrusting my sexed up manpussy. After cumming and feeling good about myself I viewed my playtime and was shocked to my once lovely perky femmy buns are not so perky. I did not expect this at the age of 51 yrs. I was going to upload this but oh no help

Whats happening, can this be cured with any excercise
