This had never happened to me before. One time me and my boyfriend were going at it really good. I had already had an orgasm but we kept going. When he was done I felt tears in my eyes. There was no sobbing or I didn't feel any sorrow or nothing. It was just tears! Why did this happen??
Sometimes after sex people can get emotional. This has happened to me before. My boyfriend was completely understandable about it. I hope your boyfriend was too. Sex is a special thing that couples share together and afterwards you can feel overwhelmed with different emotions. Usually for me it's the feeling of loving my boyfriend so much and being happy that we shared this together. Don't feel bad about it, it happens more often than you might think. Just explain to your boyfriend why you're crying to make sure he understands why. I hope he's comforting towards you and appreciates your emotions. Hope this helps!
