[El_Hombre_Grande]

So you and your 7.5 roommate drink a bottle of wine and a few beers and you saw no openings whatsover at any point whatsover in your hours upon hours of "interesting conversation?" At no point were you able to steer the conversation to playful banter regarding sex, or playfully wrestling, or discussions of massages or ticklishness, or incidental touching of any sort that would lead to an accurate read? If you can't do this, just lunge at her. Its better than not lunging.

but that's really advice for next time. In this case, you've bored her to death and she probably thinks your willy is broke. Give up.
