Is AUTHOR wrong in the post ? POST : I \[21M\] wanted to get off, but my girlfriend \[20F\] didn't want to, which is entirely fair enough and her decision. I left it at that for half an hour, until I decided that I wanted to leave and get off myself. She then got offended by this, saying that it was selfish because I could have waited a couple hours and she might have been up for it then. The thing is we're both fairly tired - we went out last night as an early birthday celebration with her friends, and ate plenty of food today. We had an hour nap together after a large Sunday roast lunch. So far when she has been too tired to want to do anything it doesn't change later on that evening.

My question is am I the asshole for wanting to leave and get off myself in this scenario?
