what happened to my penis?

Hi

When you say your penis drops do you mean it goes soft again right after you have ejaculated?  Thats normal,  as for the dark wee the darker it is, means you need to drink more thats all.  If when you do pee it stings burns or is hard to actually wee you may have a urine infection, which sex or no sex happens to both guys and girls and would be easily treated with antibiotics from a DR.  As you have said the only issue is you urine is a dark yellow, just drink more than you have been and it will get lighter as you become more hydrated.

I hope this helps

I agree with Violet Cherry. Barring details you haven't mentioned, this really is most likely it. Nothing you have said so far sounds particularly strange to me. Please keep in mind that the penis uses the urethra for reproductive as well as waste elimination, urinating afterward helps clear and clean the passage. Men commonly have an urge to urinate shortly after ejaculation. It is not a strong urge usually and it can easily be ignored in which case it will quickly go away, so it isn't really that big of a deal. Part of the reason your body does this is because there is normally a small amount of retention and urinating helps clear it. It is possible - not saying it is since since I cannot see what you are seeing - that some of the color is retained material. Your age, what you eat, how long since the last ejaculation, and frequency of ejaculation are only a few of the factors affecting how your semen appears and feels (thickness, cloudiness, etc.). This can sometimes be seen when the material is flushed through urination. Now having pointed out that this can be the cause, what Violet said really is the most likely cause, not enough water intake. While what I described can and does happen, it is seldom noticeable. So a bit of dehydration is more likely.

I am aware of no harmful affects from masturbation short of compulsive behaviors. One of the very most common prescriptions to resolve sexual or sexually related relationship issues is more masturbation not less. It is almost universally recognized as a healthy activity unless taken to extremes. I see no reason why you would need to stop or even reduce how often you masturbate.

Masturbation is perfectly normal. I know there are people telling you it is not normal. But it is normal and it is considered a normal and healthy part of sexual maturity. There are also people who insist they don't masturbate and never have. They might have stopped masturbating, that does sometimes happen for various reasons, but the majority of people do masturbate at least occasionally. For those telling you they have never masturbated? There are a group of scientists who would like to talk to them. It would be a fascinating study in abnormal behavior if they are telling the truth.

When you look around you, your friends and classmates (I am guessing since I don't know your age), and even your teachers and parents are almost certainly engaging in similar behaviors -masturbation and sexual exploration- at least occasionally (emphassis on occasionally). They may say otherwise because it is a taboo subject, but they do it too. Again, at least occasionally, and often much more than occasional.

I would be happy to discuss this with you in greater detail if you would like. In any case, without more information I would have to suggest you are doing just fine. I see no problem from what you have described, but do pay attention to the possibility of infection as Violet pointed out. If it burns during urination - I don't mean just once, once can be due to other reasons - you likely have a urinary tract infection. If you do have one, you should realize it is most likely not related to your masturbation. Let me know if you need more information on these kinds of infections.
