I meet girls via online dating. Not sure if I should be flirting on the 1st date or not.

The thing is, when you meet a girl from online dating and she gives you a date, all that means is that she likes your picture. Whether she likes how you look in real life is a completely different question. The thing is, you don't know if she likes how you look in real life until she gives you a 2nd date.

So not sure if I should flirt on the 1st date/build sexual tension or just treat it like a mini job interview. Obviously if you can tell the girl is one who is looking for a hook up, you just go for it. But all of these girls claim like they want relationships (and I meet them off the more relationship based apps, not tinder). So I'm not sure if I should be trying to build sexual tension on the first date. But at the same time, women are irrational... what they say they want or what they say they are looking for doesn't always match up with how they act in reality.

The majority of times, I never get a 2nd date, because girls don't like how I look in real life (even though they liked my pics). I thought maybe it is because I didn't flirt enough on the first date. But it doesn't add up because the uglier girls always give me 2nd dates, and I act the same with them on the first date, so that tells me that it is not my lack of flirting on the 1st date that is making me fail at getting 2nd dates... rather, it is because girls don't like how I look like in real life.
