It sounds like you have warts. So yes you have an STD. You can have them frozen off, but they will come back eventually.
It is breaking the hymen causing it to bleed, your not popping anything, your breaking through so the penis can get further, its painful for some people depending the size of the penis.
No you should not attempt this as you can bleed to death.
Not normally. See your urologist.
No it isn't. You are definitely doing something wrong.
if you were to have a pimple on your penis and then popped it, it would be painful and it is possible that it could get infected.
I dont think that saltwater alone can do the trick, buit things in the water can. If the pain continues, i would recommend you to go to the doctor.
It shouldn't. Take the dog to the vet.
The urethra is very delicate, and any rough handling, including catheter removal, will cause it to bleed.
Side effects. Don't worry.
It is a penis it just makes them die
It's very painful, go to the doctor.
You can grab it, but that or looking is it. There is no body part that has any relationship to the size of the penis.
