Shettles method

I wanna hear what everyone else has experienced or tried just for fun! Myth is if you have sex missionary you conceive a girl (this was true for my first) and if you conceive doggy style you will have a boy! Has anyone else had either of these proved true or tried the shettles method of ttc as close to ovulation as possible for a boy and at the beginning of fertile week for a girl. I know it’s a 50/50 chance but it’s fun to see if some are true!
