how long do i have to wait to have sex with my new bf?

So I'm in a beginning of a relationship, I was wondering how long do we have to wait to have sex? Like... I've known people who've do it since in the beginning of the relationship, others just wait for it. With one of my ex's we waited for a year and a half because well... he was my first one. But I don't know, I fell so different with my boo now... so confident like if we've met for so long. I feel he's the one I've waited for so long to get to me. I haven't feel this way for yearrrrs.
