being on top

Nikki • Ttc number 3 for me and number 2 for hubby! And first child together! 4yr of trying been 8 yrs since i had a baby. Baby dust to all!

okay so i have been pg twice both times i got pregnant my ex husband was on top. My husban now is never on top I am. And i know i can still get pg on top but what are my chances if the moment I get off him everything comes out? Should he been on top to get pg or does it really matter
