scot in my experience, the ones who talk about sex from the off are really only after one thing. Imagine, they are probably chatting to multiple women, only one has to say yes, and they get to get their fill without investing anything. I actually never met anyone who started straight off with dick pics and sex talk. Once I had a guy, we chatted on tinder, seemed nice, respectful etc, soon as I sent him my whatts app, I got 4 videos of him having a wank, cum shot an all. Once he had done, that was it. He basically just wanted to have a wank. Idiot. He looked so innocent and sweet too.
The ones who don't need to brag, show their wares etc but are flirty, they are the ones you should invest your time in. Unless you want ONS, then go for it.
I also left an abusive relationship (I read one of your posts up thread) and I was talking to my friend about one guy once and it looked like it was going to be difficult to get any privacy and I said well, there was always the car. And she said to me "Pudding, don't you think you deserve more than a quick car shag?". Made me realise that although a quick car shag is ok, it wasn't really what I wanted, especially as I knew I would probably never see him again. Decide on your boundaries and stick with them, some attention is not always better than none.
Still a quarter on the smitten bench here with FWB (I don't know how else to describe him, but clearly its more than that now), had a wobbly couple of days trying to work out if its what I want too or not. I always have that nagging doubt I am not enough, but getting there slowly. He is very patient with me.
