Haha nope, quite the opposite actually. If she's coming to yours, she's 100% dtf, whether there was any sexualisation in your text interaction or not. So you can lead her straight to your room. She knows what's up.

1. You can just ask "Have you had a boyfriend before" "When was your last relationship" or you can preface with "I have a question" "I'm curious about something". From there, some routes are you can ask her why they broke up.. "let me guess.. the sex was bad" if she says yes, "sorry to hear that.. most guys don't know what they're doing etc" and show sexual authority/dirty talk. You can talk about your own dating history and DHV. It doesnt have to be explicitly sexual, the fact that you guys are talking about dating history implicitly places a sexual frame on the interaction

2. Any words like long. hard, wet for example are an opportunity to misinterpret or say "that's what she said"

Re 2.:
One that I've been using lately is to say, in jest, "I only have sex after the 10th date by the way". That leads to a fun discussion, you can play around with it and often times she brings it up later again "But you only have sex after so many more dates...".
What I often do, say if you bounce to a different bar is to say, "see, we can already count this as our 2nd date" etc.
