Question about sex inducing labor

Courtney • Rainbow baby
I'm just curious about something! I am past when the Dr said I'd go and past when I had my other two boys who was very healthy! Me and my man have been having sex at night to help go into labor and tonight his stuff came out so does that mean it won't work or you think some could of stayed in? I have very healthy big boys and Dr told me it's safe for him to come anytime now so we are trying this to see if it'll help just don't know because it all didnt stay in??? anyone know?
