After a night of drinking, a sexually frustrated gay man heads into the city streets to find a sex partner, what he finds is a fast-talking, charismatic, good-looking hustler with a drug problem and a sexual identity issue.

That's a summary of a 1st act -- but, alas, not a summary of an entire plot. The gay guy meeting the hustlers seems to be the inciting incident.

Now what?

1] What becomes the gay guy's objective goal as a result of meeting the hustler?
2] Who/what stands in the way of his achieving this objective goal?
3] What are the stakes? That is, what is at risk? What does he stand to win if he succeeds -- and lose, utterly and irrevocably, if he fails?
