I was hanging out with this girl yesterday and things were going ok. She started touching me and was clearly trying to escalate things but I couldn’t do it for some reason. I’m a virgin but I didn’t feel nervous. I had an erection so that wasn’t the problem either. The more I was alone with her the less I found her attractive and didn’t want to have sex anymore. I’m going to see her again this weekend and want to prevent this from happening again.
