the earlier I convey my sexual interest in her, the more quickly the conversational will become sensual.
Yup.
First off, at a college party, social proof matters a lot. Make sure you are seen to know a lot of the people there and are always in-set, even if it's just with a dude and a HB5. Social proof is easier to fake in a college party, because you can go round hi-fiving guys and girls for no reason (and people will assume you know them) but at a random bar those people will probably leave you hanging.
Basically, if you spend 20 minutes talking to a girl about classes and mutual friends without escalating or making your intentions clear, she's gonna start assuming you're not sexually interested in her, or you're a pussy or gay. If you make it clear either through your words or actions that you think she's cute within the first few minutes, then you'll know straight away whether she's interested in you or not, and you can then escalate with confidence or open a new set.
TIP: Your value is highest when you are in-set with an HB or two. Whilst interacting with them, force IOIs from other HBs in the room with a smile, wave, wink or raise of your cup. That way, if you get blown out you can immediately approach a girl who you KNOW likes you, and you're never left in the awkward situation of having a set leave you standing by yourself looking for someone you know or another set to approach.
