Gimme a Kiss is a YA mystery/thriller originally published in 1988. I bought my copy new.

Review:
Jane Retton is a teenager who uses her diary to imagine a slightly better life for herself. In her diary, when Kirk, her friend Alice's ex-boyfriend, asked her out, it was super-romantic and perfect. She's in the process of writing about their perfect first time having sex (in reality, Jane has never had sex) when she's interrupted. She forgets to put her diary away, which, unfortunately, soon leads to Patty, a cheerleader who hates Jane's guts, getting hold of the most recent entry, making copies of it, and passing it around school.
Jane is deeply humiliated. It doesn't help that Kirk doesn't deny the events mentioned in the diary and adds fuel to the fire by confirming that the handwriting is Jane's. But then Jane has an idea, a way to temporarily get back at both Kirk and Patty. Except something goes horribly wrong. Now Alice, one of Jane's friends, is the only one who can say what really happened. But did she actually know everything, and is she telling the police the full truth?
