TMI- TTC and Sex

So, weird question but no place better to ask than here I guess to help me 🤷🏻‍♀️

My husband and I are ttc window now and after he “does the deed” inside me he pulls out pretty quickly(1-2seconds after). There are a lot of “leftovers” afterwards and I feel like maybe not enough is getting far enough to Conceive.

I started tonight laying with my feet up afterwards to maybe help and will be getting pre-seed lube maybe to help, but wondering if this could possibly be the reason it’s not happening? Anyone else have this happen? Or maybe he just is very “endowed” enough to just have ALOT when he finishes so it seems like a lot of leftovers 😂
