A Woman Has Some Questions

Okay so tell me this:

Is it unreasonable for me to not want to have sex on the first date, or whatever the fuck you call online meet-ups nowadays.
This is not unreasonable. Why is this a thing? Why am I feeling, like, crazy for wanting to set this boundary. Why do I feel crazy for saying, "No." Even if I have wanted to have sex. But after having sex on the first whatever-the-fuck-you-call-it with a couple of guys, I don't like it.
Also, figuring out that this is a determining factor as to whether a relationship of some sort moves forward or not? Heeeelllll to the no. That's so much pressure. I don't want that. At all.
This is okay. I have to keep telling myself that this is okay.
I feel like this has maybe already cost me a relationship, but if that's the case then that wasn't something I needed, right?
Why am I even questioning this?
Is it crazy for me to have a standard of respect? Like respecting me is taking me on a couple of dates, see how things go, and then ASK/DISCUSS when we are ready to have sex. That's what I want.
I have a hard conversation ahead of me with Freckles. It's not going to end well, I don't think. I think that he will probably assume that I've been leading him on or something.
But I haven't been. I'm allowed to change my mind. I'm not obligated to him or anything. My, "WHAT IN THE FUCK ARE YOU DOING, DEANDRA?!" moment is really, truly making an impact.
Setting boundaries is one of those things.
I'm basically doing a 180.
But that's okay.
Right?
This is hard. Not because I don't know what I want; I do. It's because I know what I want, and the way this is going is not it. The way this whole dating thing has been going is not it.
This is just not it.
And that's okay.
Right?
