Will sex with a buttplug in, make it fall out

Will having a sex with an anal/butt plug make the plug fallout? My butthole isn’t loose (never had sex anally lmao) so I don’t expect it to, but I was thinking sense my holes are close together the pressure from his d*ck could make it slowly pop out which is a noooo no 😂 I want it to stay in while we’re f*cking, ig worst case scenario I ask him to lightly hold his finger on it lmaooo. Also no I do not mean sex anally with it the plug in, I meant regular sex but having buttplug in as well to add to it
