Hi. I met this girl through Tinder, we went on a date and it was fun. The only “problem” was that the convo’s were pretty “casual” maybe even boring. And even now when we’re texting it’s still a bit of casual.

How do I shift the conversation to a more spicy/flirty/maybe even sexual level so I can ask her out again, without looking like a fuccboi or somebody that only is interested in her looks?
