Goodness Shadix!

NOT ALL WOMEN WANT TO GET IMMEDIATELY MARRIED.

I'm sorry, but I just needed to put that into all capitals because I think you totally fail to read anything that doesn't fit your frankly, rather sexist, assumptions.

The best way to find casual encounters is online. Or at a club if you just want a 1 night stand, which doesn't seem to be what you want.

Online, on sites like OkCupid, Plenty of Fish, Match, etc, you'll find plenty of women aren't looking for anything serious.

Even if they are in the long run... no one starts a relationship going "I am going to make this guy marry me!". No, instead, they want to get to know you - which is that whole casual thing you want. Either they will break things off with you when they find out you're not what they want or that the relationship won't develop how they want... or they'll be happy with how it is... or you'll decide to end it.

To help give you some more evidence - I know multiple women, in their 30s, and homeowners with good careers... who do not ever wish to get married. They want relationships, but they are both clear on the fact that the men they get involved with will NEVER move in with them.

You need to drop your preconceived false assumptions about women.

And just because you don't notice men blatantly hitting on women and being inappropriate does not mean it doesn't happen frequently. You are not the recipient of it, so no matter how much you think you're paying attention and watching them (which is kinda creepy and would likely turn off any women who notice that behaviour).
