I’m 18 years old, female, and currently living in a suite-style dorm. The setup includes two single rooms and one double. I share the double with my roommate. She is very devout in her Christian faith, while I am not, so naturally we disagree on certain personal matters.

One evening, she and one of my close friends went out to an event for a few hours. I stayed behind in the room and spent some time chatting casually with a guy on social media. Nothing unusual, just conversation.
As the night went on, I decided to take a private moment for myself. I lost track of time, and just as I was finishing, I suddenly heard the door open. I was startled and embarrassed. I quickly pulled the covers over my face and politely asked them to step back out so I could compose myself.
My roommate reacted strongly. She exclaimed, “That’s so disgusting—you’re lucky you’re funny sometimes!” and stormed out of the room. Her words stung, but I tried to remain calm.
Later, I went downstairs to talk with them. Instead of understanding, they portrayed me as some sort of villain. They insisted that I should stop engaging in private self-relief altogether, even though I have never done it in front of anyone or while someone else was present.
I found this demand unreasonable. What I choose to do in my own bed, in private, should not be their concern. It is a personal matter, and I have always respected boundaries by keeping it private.
To make matters worse, they have occasionally called me names, labeling me promiscuous, even though I am still a virgin. I do chat with guys online, but both sides know it is casual and respectful.
Their judgment feels unfair and intrusive. I believe my roommate’s discomfort stems more from her personal beliefs than from any actual harm I’ve caused.
So now I’m left wondering: am I truly in the wrong here, or are they overstepping into my private life?
