So I’ve been thinking about this ever since it happened. I was getting into some foreplay with my ex girlfriend. We we’re kissing and I moved my hand lower and she just laid down. I started fingering her but then I lost all erection,I felt happy because I was pleasing her but I was not sexually there. I don’t know why it happened, when we were kissing a few minutes before hand I was hard as steel. It could’ve been a variety of things. It started to feel like a chore at the end of the foreplay and I went home.
