Delusional thinking. Sure there are people who will fuck someone without knowing their last name but that is not nor sure it be the norm.
Why would I fuck you if I don't know your STD status or mental health or if your not an abuser and so on. This is why I chose to remain a virgin and probably single for the rest of my life. I hold certain values that is hard to find in the dating world 2018. I rather wait till marriage for sex.
I have heard of this way thinking before... men expecting the most intimate aspect of a relationship from a woman after a few dates and if she doesn't give it up they "ghost" her.
Much rather be single then deal with bullshit ass humans.
