I'm really confused why I started full on crying??

So I was just getting myself in the mood and I slipped my dildo in and it felt so good I was so wet and I kept going and then I felt a tear roll down my cheek which had happened before because it felt so good but this time I continued masturbating building myself up to climax and I kept cry like full on sad crying and now I'm bawling but I'm still horny but every time I put the dildo back in I cry it doesn't hurt at all and I made sure I was wet enough to start... I'm so confused is this normal???
