Is AUTHOR wrong in the post ? POST : So me (19M) and my girlfriend (17F) of 1 year have a disagreement.  We only see each other during the weekend. During the week I study in a city far away from the place she lives.
I watch porn during the week. She still dislikes it that I do it, but has grown to accept it. The conversation about porn come up today again and she now wants me to tell her i do it, while doing it. She says it calms her to know it. 
I don’t agree with this however. It ashames me and makes me feel uncomfortable. After I did the deed, I just want to get it out of my mind. It’s just something I want to do alone for a quick relief, no strings attached. 
I don’t really know how to put it properly in words how I feel. Do other guys feel the same?
Am I unreasonable for not wanting to tell her immediately after I watched porn?
