I find it to be very uncomfortable, I’m used to having my legs crossed when playing sitting down
I don’t have any particular problem playing sitting down by moving my pedals away from me so that the angle of my leg allows for comfortable playing.
Even without using a pedal, it is a bad habit which prevents the good holding of your instrument and especially which is detrimental to your health (bad blood circulation).
I don’t know, I’ve watched a lot of videos about guitar positioning, but none of them ever really felt right. With my legs crossed I feel like at home. Maybe my guitar is too small for my body.
