Background:

Mid 20s white male. Happily married. Good job.

My wife and I have decided a few months back to begin trying for child. At first, I was able to get up with no problems. Daily sex was great. Now that we're into our 2nd, almost 3rd month of trying, I have been having difficulty getting an erection. In the past, I would just touch my penis and could get an erection. Now, I can try for 15 minutes and get a half full erection. I am mentally turned on. My body, does however, feel just entirely too relaxed. We have been remodeling and I have become the homeowner who never stops. When I sit down, I get bored and go work on something. My wife thinks something is wrong with her, but she is a very beautiful and great woman. I LOVE having sex with her. I read some places it is stress. I am stressed, but when have I not been? I do the finances. I make sure everything is done at home. I have considered going to the doctor, but I am rather haunt to do so.

Are there over the counter vitamins I can try? I have not "wacked off" in days or had sex in days and I am just flaccid.
