Is it normal that i cum different volumes depending on position?

If I masturbate laying down, standing or seated and cum, I cum a fair amount with a few spurts, increases slightly depending on duration of masturbation. However if I do it on my side, one leg out at around 90 degree from my torso so I cum on my inner thigh and cum, I shoot a huge load and it often has 6-8 spurts which go beyond my knee. It feels better, orgasm is longer and stronger and have at least another 6-8 contraction with smaller spurts.
