So you think 3 dates over 3 weeks equals a 'relationship'? Because that's what you have said.
If not, how many dates equals a 'relationship'?
Apologies, at the start of seeing someone, then. I think that's fair. You wouldn't want to be weeks into dating someone to find out that that they wanted an open relationship.
And on Date 1 you'd actually say to a man (or woman) 'Look, I want you and only you at the moment. Don't date another person from now on. Just me. I want exclusivity.'
I think any sane person would run for the hills if given that kind of speech.
I've never made that kind of speech. I've never had an "exclusivity talk". When I've had a date with someone and it's gone badly, then we don't arrange to do it again. If it goes well and we get on, then we'll arrange to meet again and I wouldn't date in the meantime. This is the norm for my friends and I.
Obviously, after a few dates, you might tell someone that you are looking for a relationship, per se, not just dates.
Maybe we're meaning different things when we say dates? If I wasn't looking to have a relationship and was meeting up with someone as friends then I wouldn't call it a date. I've never had an experience where, after a few dates, someone felt the need to tell me that they were looking for a relationship... It's fairly obvious by the fact that we keep going on dates.
Your style of dating suits you. It's not what others like @TedMullins do and you aren't in the right, by any means. Implying other people have no morals because they don't take your line is really unfair.
I've not said that they have no morals. You're extrapolating quite a lot there. I do think that, if you're going to see several people at once, you should let them know. Because, while I agree there's nothing wrong with dating or having sex with multiple people, it's only fair to tell the other people involved (by which I mean the people you're dating, not a one night stand), so that they know where they stand.
