Awkward Play Scenes

I’m in a play with my acting troupe, and I got a really good part. But, I admit it, I suck at romance scenes. And in this play I’m a sexually active teenage girl and I have to kiss my “boyfriend” passionately, dirty talk to him, and basically hump his lap in several scenes. Just so you know, it’s an “adult” play, and I’m 17 years old. But my “boyfriend” in this play is actually a socially awkward, perverted nerd in real life. And he’s been hitting on me behind the scenes ever since we got our parts. I’ve already been forced to make out with him eight times during practice, and his mouth tastes like morning breath and boogers.
