TTC - sperm running out

M.Jane • Married 💍 🏡 TTC baby#1

Hi all im new here... and apologies this might be a really silly question 🙈 But i have noticed after having sex alot of the sperm just seems to run out. Is this normal? Is this whats preventing me getting pregnant? Me and my husband joke that oh I'm just shooting it back out but is that even possible?
