If you only smoke one blunt are you participating in doing drugs? Yes, but it's important to note that a person who does zero hookups, a person who does one hookup, and a person who does recurring hookups are all different kind of people. One is repulsed by the idea, one is curious but wasn't sold, and the last tried it and liked it. You get to decide what kind of person you are, but your actions shape how people think of you.
