STD Question

I'm pretty sure crabs lasts indefinitely without treatment, as they constantly reproduce. Not sure about the latter, sorry.

All the best.

 

Yay! Time for a random lesson on genital parasites!

First of all you cannot get Lyme Disease from pubic lice (Pthirus pubis). Lyme disease is a bacterial infection that is only carried by the bite of the blacklegged tick (Ixodes scapularis). So no need to fear that from this innocent pubic parasite.

As far as P.pubis live span you need to know something about their life cycle. Humans are the definitive host for P.pubis and they have no intermediate, meaning that they can complete the entire life cycle using a single host, and do not require transmission for survival (an example of a parasite that does is tape worms).

It starts with the transmission of the female who has already mated or a male and female pair. The happy couple mates and deposits eggs near the shaft of the hear follicle. The egg hatches and the nymphs are born. The nymphs then mature and pair off to lay more eggs of their own. This means that not only can you stay infected pretty much until you die without treatment, but that the number of P.pubis you are carrying will increase until you reach carrying capacity. Carrying capacity is a term to describe the number of organisms that can sustainably live in the area given the limitations of resources. So basically since P.pubis cannot live on the head or body hair, the limitation is you running out of room in your genital hair for the laying of eggs.

Pubic lice our one of man kinds oldest companions and the three distinct species are thought to have evolved as a result of our loss of body hair, but evolution is way beyond the scope of your question and I will only go into that if you are interested.

 

^^excellent medical explanation by CatofOld. Thanks Cat!
Also, there is no barrier method to protecting yourself from crabs. Skin-to-skin contact with an infected person has the possibility of transmitting a pregnant female or a male and female pair who will multiply and inherit your...pubic region.

 

Frottage.

 

Quite simply, they don't. Most people get crabs cured immediately so it's generally safe to assume the other person doesn't have them.

They aren't exactly hard to cure either, and seeing as they are curable it's not as big a deal as the main safety priority of HIV is.

All the best.

 

This sounds like a personal question, and as my disclaimer I would advise you to see your doctor if you think you might have an STD.

Okay now on to your question, yes not dirnking enough water will cause more concentrated urine. When the body senses a rise in the osmolarity (concentration) of the blood it triggers the pituitary gland to produce ADH (Anti-duretic hormone). This hormone causes more aquaporen channels to be embedded into the walls of the collecting tubules, which are part of your kidneys. These channels allow the body to pull more water from the filtrate (your soon to be urine) creating a more yellow and high concentrated urine to be produced. This urine due to being a waste product and much more concentrated is more acidic, but should not burn on the inside, but can sometimes feel a bit irritating to externals skin. Burning (like sharp razor blades coming down) can be a sign of a lot of things the most common among them being an STD or a UTI.

As for using the toilet and it burning one time, I would say most likely not an STD. It could be cause by any number of factors including things in your food (capsicun from peppers passes into the urine and can do this if you are eating just huge amounts) or something like a sore on the outside of the gentalia.

So in recap:
1) Use protection every time and go get tested if you haven't
2) Yes the body concentrates urine when you are dehydrated
3) 1 time of burning that clears on its own is kind of unlikely to be of infectious origin.

 

If you wish to calm your conscience then yes, but otherwise I'll say that the definite answer would have been discovered in those 2 tests. Kissing a guy with HIV has basically 0% risk as long as you have no open sores or cuts in your mouth. Even if you do, the HIV concentration in saliva is either none at all or very very little, to the point it's unlikely to get it even if you have cuts.

All the best.

 

There are tests that can detect it in weeks. Generally each test is extremely accurate, each one is bound to give you the correct answer, 2 has a ridiculously low chance to give you a false reading. If you're really worried I'd go get 1 more then leave it at that. I'm sure you're fine though.

All the best.

 

These days, the test at 4 weeks is >97% accurate.

 

Ok I'm half joking with this, but have you been reading WebMD?
