Female orgasm + conception 🤔

I have been reading article after article and forum after forum about different things that increase your chance of becoming pregnant. 
 
One thing that stuck out is that a female orgasm can help move things along places and gives you a better chance of pregnancy
 
My question is... if my husband finishes first, will it help if I am able to reach orgasm after? If that happens, a lot of times he will help me finish with his hands or I'll finish myself. We do this before I get out of bed to clean up or pee.
 
Sorry if this is TMI. 🙉
