You get a very limited chance to make a good first impression during online dating. Here are a few tips to keep you from messing yours up:
Have what you’re looking for, not what you're NOT looking for. Otherwise you’ll sound negative or scorned, which is extremely unnatractive.
Unless you’re strictly looking for hook-ups, don't. And even then, most women know that sex is on the menu if a relationship moves forward without you writing about it.
You’ll look older, more tired, and more dazed. Opt for non-flash photos to help out with your face.
This comes up all the time, but seriously, don’t. First impressions matter--write a sentence or two about yourself that actually sounds like you got through high school.
Obviously start the chat on your phone or online. But after a few back and forths, it’s time to meet up. Don't’ waste each other's time, otherwise she may get bored and move on.
