I'm writing a book that will fit more into the Young Adult fiction genre than any other. When writing my two MC's first real romantic encounter, how much description is too much? It will go no further than them kissing/making out (that's all I'm describing. Anything further I'm leaving it to the reader's imagination) but I want to make it descriptive enough that it gets the reader's heart racing but not enough that it makes the reader uncomfortable. I also don't want to spend a whole page on it, but also not just a short paragraph. Any suggestions?
