If they are like open sores or sometimes almost blister like bumps that pop or ooze puss and what not.It could easily be be herpes, my friend who is 17 called me crying freaking out about these spots she found that were really sore and would open up then scab over and heal but were very very painful at times so I looked up all the info for her she went and saw the doc and what her symptoms turned out to be were herpes. Dont worry that might not be it. You need to go to the women doc and see whats up ... Dont be scared stuff like this can happen to anyone and everyone... Not just "certain" people. Don't stress it just be responsible with it and go to the doc it could turn out to be nothing and if it is the -h- they have great medications now to where you will get to where you will break out maybe once a year and get to where you are break out free.
Dont worry.. Just go get it checked
