The thought of getting your partner pregnant if you do not use a proper protection may also play a role in losing the erection. You may need the support of your partner, avoid anxiety keep away from any past emotional distress. You may take SildenafilViagra for support. Get connected to a GP, if you think you are suffering from Erectile dysfunction. Take protein rich diet, get treated at the earliest. Hope I have answered your query.
