One perk of DM-sliding is that you can skip a formal greeting, because the person can just look at your profile and see who you are, says Samantha Burns, LMHC, a dating relationships expert. « Just jump right into a comment or question, » she says. Your thoughts about a link they tweeted or event they put on their Instagram story will make more of an impression than a generic, « Hey, what’s up? » And if you want to send a sexy photo, just think about it before you do, Hope says. Even though basically everyone has and sends sexy photos, your recipient might not be expecting it from a total stranger right off the bat.
