Thanks for contacting HCM with your medical questions and concerns I am sorry to hear that you are having problems with keeping erections. This is a very common problem and one that men face when they get stressed. The stress could be both positive or negative. in your case I would venture to guess just being married there is stress on your performance. This will cause erectile dysfunction. In my practice I see this frequently and I prescribe Viagra, Cialis or Levitra. in your case since you are newly married a daily dosing of Cialis may help you overcome your problem. Usually after getting over the stress of newly married and having erectile dysfunction I will stop the medication. Just by having positive results will bolster your confidence and allow for regular erections. The other concern you have is the size of your penis. This has nothing to do with erectile dysfunction. It may cause you anxiety about performing but you and she need not worry. Hope this answers your question. Please contact us again with your medical concerns and questions
