Based on the information provided, sending frequent selfies on dating apps can be a normal part of dating behavior, but it can also potentially indicate attention-seeking or even signs of an online dating scam. While sharing photos is common in the initial stages of an online connection, an excessive number of selfies, particularly if accompanied by strong displays of affection or requests for financial assistance, may be red flags. It's important to approach online dating cautiously, maintain healthy boundaries, and be vigilant for any suspicious behavior that could suggest the person is not who they claim to be.
