Okay, let's break this down: nothing intimate has happened - yet - but she seems interested, she's known as a tease, he's wondering if an invitation to her place means anything and you find it offensive that
we implied sex?
In most people's parlance:
intimate = reference to sex
tease = reference to sex
invitation to one's place = reference to sex
posted in sexuality forum = reference to sex
If you took offense, then I would suggest that you look to your own verbage for any confusion.
If what you meant was, "do you think this may mean she's interested in pursuing something?" then you would have gotten more responses along the lines you were looking for.
In which case, I would direct you
here.
