I am really afraid this is something serious o:

Could it be the color of the dildo that came off?

you might want to get tested because that is the symptoms of some stds and hiv.

STD's? HIV? I never had sex before. Only played with my own toys. Does that make a difference?

hello maybe you have been a bit rough and not lubricated and this could be possible bruising as the area around the anus can be dark in colour.if there are no lumps its not possible for hemarroid as they are sometimes this colour..remain from using your toys for a few days and see if the colour changes..if it does then its been bruised tissue.
if it still worries you get it checked out.
hope this helps you and remember when inserting anything analy make sure its comfortable and use plenty of lubricant if you feel any discomfort stop..and importantly keep them clean.
good luck.
ioka.

Thanks a lot for the help. :3

Any other suggestions are welcomed :3

hey i have the same problem... just noticed today
i wanted to ask if you still have it after a month or so?

Yup it is still there. Me and my boyfriend have decided it must be dye from my toy. He calls me blue butt now *chuckles* Anyway. It doesn't seem to be anything unhealthy. I've had no problems with it.

Do you use toys?

no, but i am able to find things around the house which i can say are not blue.
did you visit a doctor at all and ask what it might be?

I didn't i'm afraid.. I know it might be the right thing to do in these cases, but a friend who plays with toys too, suggested it was the result of being too rough back there. So the color is actually the skin being bruised by too much stretching.

I just typed in the wrong place hope you get it.
