Hello, Some people like you tighten their whole body muscles during masturbation and at the time of ejaculation causing pain in body/ legs or back.  Learn to do in a relaxed manner. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.  V. Anand, Psychologist
