I am a 41 year old female and have never experienced this before.  I need help.  I started having a pink color on toilet paper when I would urinate and wipe a week ago.  It has been like that everyday since.  Yesterday I started having a slight itching sensation in my vaginal area.  Now today I woke up to shower and it feels sore to the touch and swollen.  I have no open sores or anything like that.  I had unprotected vaginal sex 3 months ago and unprotected oral sex 1 month ago.  I have never experienced any of these symptoms like this before.  Could this be some kind of std that's causing this?  I read online and of course it named many std's it could be and even named herpes but I assume this wouldn't be herpes because I don't have any open sores or anything like that.  

Welcome back -- but I think I'm seeing a pattern here. STDs seem to be the first things that come to mind when any new health problem pops up.---
