How do you ask for 🍆 pics from a guy you’re dating ?

Okay so I’m dating a guy (about a month) and I really like him but before things go any further I want to know what he’s working with, call me shallow but my Ex who I LOVED had the smallest 🍆 ever I was unsatisfied the entire relationship (he treated me like trash that’s why we broke up not because of his size) and I can’t do that again sex is important to me and I don’t want to get into another relationship without seeing it first. How long should I wait to ask? How can I ask without him thinking I want to bang? I just want to see it so I know if I should continue this connection or not.
