Thanks for contacting HCM I am sorry to hear that you are having erection problems. I agree with you that over masturbation masy poor erections. I hope that by abstaining for masturbation that your erections will be better and you can have sex with your girlfriend. If you still have erection problems then I recommend you see about getting a prescription or Viagra or Cialis. This medications help improve erections. I also recommend reducing stress. Overall stress can cause sexual problems. I recommend starting relaxation exercises and meditation to reduce your overall stress levels. Hope this answers your question.
