Hello, when you massage your girlfriend, you should pay attention to the technique, strength, time and so on. It depends on your girlfriend's physique. If not, you can find some videos to learn. In addition, if your girlfriend is afraid of pain, you can tell her more jokes during the massage, which can also relieve her tension and pain. One more thing, if your girlfriend has symptoms of dysmenorrhea, you can give her a cup of brown sugar water before the massage, so that it will not hurt so much when you massage. I hope my answer can help you! .
