My boyfriend and i are both literal psychopaths. we don't hurt people physically, but we take joy in hurting people mentally. messed up i know. but we can't it. are we a safe combination of mentally insane? as a couple?

If you take joy in seeing people hurt mentally, it could escalate to physical torment quickly. This is dangerous and will turn into a crime.
 It can cause people to commit suicide, and have mental issues as well.
You are not only ruining yourself, but others.
You and your boyfriend need serious help.
 I'd talk to your parents. At least you are noticing this now, I hope you plan to become better and learn to change your ways. 

There are a couple of answers.you could have an infection, a sti, std, or other problematic health issues.i would recommend going to the doctors, if not, take a shower and wash down there, then wait a couple of days, and if it’s still there, then is when you should go to the nearest or trusted gynecologist of your choice.
