can lots of sex cause labor?

I've heard of people using sex to go into labor, but how soon would that method be effective? I'm 36 weeks, measuring ahead and we have sex multiple times a day (for some reason my libido is through the roof and he doesn't seem to mind 🙄😂). I haven't been given any restrictions though, so I just want to know what the likelihood of going into labor as a result of sex would be. Thank you!
