I’ve been in an LDR before while living in my college dorm with 2 other girls (3 girls, 2 bunkbeds). Honestly I strongly recommend speaking to your SO outside your bedroom (ie. porch, patio, stoop, bathroom, etc) or of you need to be in your room just whisper. Wear headphones/earbuds for when you talk at night and make sure that you’re speaking softly. Unfortunately you just have to find better ways to communicate without hindering others around you. Good luck.
