No, only if you have sex with somebody that who have STD.

And how old are ya?

Young.

You can give yourself an infection from that, but you can't give yourself something you already had.

I mean before I did that I wiped my finger off, so I don't know if that could of helped or not.

Yes.Its called AutoInfection.Seriously.

im suprised your still alive

That reasoning is so far beyond 'kinda dumb.' I do not care how old you are. You are a retard.

The only way to get an STD is to have intercourse with someone who already has it. You could however give yourself an infection but nothing serious. You should look up on the internet information about STDs and how you get them. The internet has some useful information about all the STDs out there including Aids, Chlamydia, Syphillis, Pid. You need to educate yourself on this, good luck

A.I.D.S. is not a STD that you immediately can contract. H.I.V. is. If you are going to insult others, do it in a non-biased way. H.I.V. leads to A.I.D.S., but it is different by a lot.
I am not trying to be an asshole.

you have ass aids

ladyoftheworld is right
Educate yourself on STDs.
Just a little info....The kind of activity you described can give you a bacterial infection. Your mother might have told you to wipe from front to back. Same concept...
Your body has natural bacteria that is normal for that certain area but it can cause problems if it ends up in the wrong place. I am just trying to explain this in simple terms.

you should have out your finger in your mouth afterwards

no, but you can

but you may get pregnant

no but you can lose ability to shit

ARE YOU KIDDING ME? HOW DO YOU THINK WE GOT AIDS?! STOP THIS IMMEDIATELY BEFORE YOU CREATE AN EBOLA OUTBREAK!!!!!!

If you're a girl you can spread bacteria from your anus into your vagina by doing this. This can lead to infection such as cystitis, which will basically make it sting alot when you pee. You can also get this by wiping improperly. Other than that no, you can not get STD's from yourself.

If you're a guy, it's hard to cause an infection by doing such things.

You won't get an STD/STI because there called "SEXUALLY transmited infection/disease" for a reason!

But you should definitely wash your finger in water and soap if it's been in your ass before you "experiment".

you can get bacterial infections... wash your hands after and before... and shower often... but i suggest going to planned parenthood (even the web) and fiding out what stds come from where and how to protect yourself... and what symptoms they have.
