How you will know if you choose the right one?

I've been here for a while now. But I haven't meet a person that is right one. Sometimes I encountered people who asks for too much. They put in their profile they are looking for a serious relationship, a good woman, and putting on capital words NO I DON'T SEND MONEY.
Wich good at first.. But once I started having conversations on them they start asking for nudes.. Or into sex topic. I mean dude.. Are you really looking for serious relationship or just having online fun?.

It is really hard to find Mr. Right at this time.

Any advice please
