Okay so I need like a ride lesson in like 2 days! I wanna try something different with my friend and I wanna try riding! I'm practicing at home but I have a few questions.... Are your inner thighs supposed to hurt? Do I need to start stretching my legs to get used to the position? Like I got the motion but I don't have the correct position.
