Sex Position

For those who already have children or are currently pregnant what was the sex position during ejaculation? I'm a bigger woman and my husband and I have tried many positions none were very successful nor did they feel good. But, I'm gonna be honest the only position that can actually make me orgasm is doggy style. Which I feel when he ejaculates, everything just spills out bc of the position. What are your thoughts on this? Or maybe some tips?
