Does my situation sound STD related?

[Khelbin]

Hello, I'm a 21 year old male and have issues with my penis. I have always masturbated regularly, nothing excessive I don't believe, but I always was in a certain position when I climaxed. Now I find it nearly impossible to climax without being in this position and am wondering if there is an STD that can cause an inability to ejaculate, or even a loss of sensitivity, which I feel may be present as well. I do have diabetes, and it is in good check at the moment, no problems to speak of, but I also have a concern of this being more fuel to the fire. To demonstrate how bad it currently is, I can get off, but not unless I receive oral sex for about 45 minutes, if I can keep it up. I tend to lose erections after a short time, as this is another symptom I'm not certain about. I lost an erection mid-** the other night, and it was quite embarrasing. Is this an STD of some form, or could it be Retarded Ejaculation and severe densensitivity? I've looked everywhere and have seen one urologist who shrugged me off because I'm a healthy 21 year old, as well as my General doctor, who did the same thing. I'm making an appointment with another urologist tomorrow, but would like to know something soon, as this is becoming somewhat of a focal point of my life.  I sincerely thank you for any input you may have.

Ok well it is not an STD if you have never had sex, so rule that out.
if it's mental the best thing to do is to see a therapist to help find and deal with the issue.

No I'm still a virgin, I plan on abstaining until marraige, and this also I feel has played a part in my psychi, although I'm not sure., And to Whatsgoingon9, no, I really do appreciate your opinion as I have also thought it was a psychological issue, I am going to make one more appointment with a urologist just to insure it's nothing physical, then I will begin taking steps of the psychological mindset in order to help. Are there any specific steps one can take to help fight the mental block this has begun creating?

Thanks again guys

It could be mental. Have you had unprotected sex at all?

I hate to share my opinion for fear it is insensitive, but please take it in a constructive way. I think you may be psyching yourself out. When people masturbate in a certain way or position, they get used to that and its difficult to break out of that pattern and climax another way. The more you worry about it, the more difficult it becomes. As far as desensitivity, that may be an issue. I am not sure what would cause that. Good luck!
