lady advice

Okay so I'm just wanting advice from you ladies... for everyone who has gotten pregnant, is trying to get pregnant or who got pregnant and didn't plan for it... does everyone's man just always finish inside of you guys or what??  Because my man swears he knows I'm gonna get pregnant here soon and although we'd all be super happy and thrilled, he always pulls out. It's sort of just been a thing. I mean I don't want him to, but at the same time idk how to tell him that I don't want him to pull out without him thinking that I'm like I'm trying to force something to happen because I'm not... I just feel like we all would like an unexpected pregnancy but I don't see it really happening if he always pulls out. It's like he doesn't wanna plan to have one but he'd be totally happy if it DID happen... advice PLEASE??
