Along with what SteelTempest and Fylimar wrote, you also have an option to leave the scene at every step of it if you are uncomfortable. Same with Shart. In my first run, she invited me to share a bottle after the party and because my actual love interest had a bomb in his chest, I accepted. She indicated that she wanted to be kissed in the morning, I didn't, she was disappointed but we had a chat about it and things were fine. Her little disapproval always makes me sad, but overall it is a very lovely scene.
The point that intimacy doesn't mean sex is also very important for Gale in general I think, because he is written as a very emotionally open friend or lover. Even his romance is extremely dialogue heavy and focused on emotional intimacy.
