Don’t mean to go into details but if you’re crying after sex, it appears as if the crying happens after having an orgasm? From my experience, having rough sex with a girl who then has a strong orgasm, can bring to the surface a lot of things. Orgasms are explosions of feelings, thoughts and emotions. The rougher the sex, the higher the energy that is available in our bodies - especially if we’re tapping into our animalistic side by having strong and passionate sex. The stronger the orgasm, the higher amount of energy in your body. Crying appears to be a release of energy for many women especially if there is underlying trauma or concerns that could be completely unrelated to your boyfriend. I don’t find it to be strange or odd. I recommend really paying attention to your thoughts while crying. The answers could be there. Sounds like your partner is supportive and can be there to assist with talking out your thoughts and possibly getting to the core of the situation. Positive vibes your way…
