Why do I attract jealous guys?

everytime i meet a new guy everything always starts off good at the beginning & everything is cool but as soon as they date me or things get a little serious they start getting jealous asking who im texting or asking "whos that " if they see a pic of a guy on my phone. If we just started dating what would make a guy get that easily jealous so soon? this happened with 2 guys i waz with before
