As you already know having an erection is not that difficult as you think. As long as you are doing everything very carefully and you do not take any other medications with Sildenafil, then it will give you a remarkable erection and you will be certain that your erection is stable and firm. Write us at our email address and specify your question. Better ask all your question and you may even ask something about your ED problems and whether or not you are able to intake these particular meds. Some men are usually very shy and kind of ashamed to talk to a real doctor that is why talking to our managers online is not going to be very shameful and difficult for you at all.
