Why did he want me to smoke marajuna with him?

Hi my name is Kimberly. I met this really cute guy named Richie at my job. We talked for 15 minutes then exchanged numbers. He called me the following night to take me on our first date. He took me to a dark beach but it was romantic. We stayed in the car because it was cold. He was grabbing and touching my and we were making out. He pulled it out and I gave him a b.j. He finished in three minutes. We had a really fun date. He called me the following night for a second date.I gave him head in the movies and he promised to reciprocate. After the movies he took me to a romantic water front where you park your car and enjoy the view. We started making out and he pulled out a bag of weed. I never saw or smoked before. I started coughing and he kept yelling at me telling me to inhale it deeper. Why did he want me to smoke weed with him?
