Unprotected sex HELP!!!

I want to have unprotected sex with my boyfriend (he won’t be coming inside me at all) *pull out method*😂 but anyways, me and my friends were sitting down and having a conversation about if pull out really works or not and all of them say that as long as he doesn’t cum inside you I should be fine. “But what about precum” I asked, they said “just suck it off lol” and so like I was thinking and thinking is it a good idea to have unprotected sex? None of my friends are pregnant so 💁‍♀️ idk HELP!!!!!
