Umm... I'm guessing you don't have many friends?
Since such a line is not out of the ordinary between friends. You might claim that it's a bit weird to be considering people you just met friends, but some people do just click pretty quickly. Given her brash, open nature, Aylin would likely form frienships quite fast (Much like Karlach)
You're hardly "friends" with Aylin at that time. More like aquaintances. If an aquaintance said that to me, I'd get gone in a minute because I don't associate with people who are so insecure that they have to flagrantly display their sexuality.
