Depends on your definition of "recently".. If you talking a month or two, then kick rocks..It a shortage out here in our favor.

If you are talking a few days or even with a couple weeks time frame, dude getting upset can pretty much be sum up in one of two scenarios:
1. He thought you were an easy jump-off from the start, and had no intention of investing any meaningful time to get the pussy.
2. You are probably moments away from ending up at the station filling out a report as why you stabbed/shot dude, or talking to a counselor on a victim crisis line somewhere. All because you didn't heed the signs and invited an overly thursty cat in, even after he exposed himself to you.
Disclaimer -
Scenario #1 is more often than not brought on by mixed signals dude received from the female while at the club, bar, etc... vying for free drinks and a plate of hot wings, or that slutty "come fuck me" dress you were wearing when you gave him the digits.
