It could be, but also maybe not.
The best thing to do is get it checked out, because if it is, you really wanna know, so you can protect others from getting it.
But dont WORRY...its maybe scary to have to go to a doc and ask him to look at your genitals, but hey, thats what docs are for, and they are SO used to it!!!;-)
Pls dont ignore it, or just think its nothing, i mean it could be, but rather know, i got herpes from my boyfriend because he chose to ignore the sores he was getting, and didnt tell me...its just so much better to KNOW, even if hard.
So, bite the bullet...get it checked, and maybe its nothing to worry about...and even if it is herpes, its ok, your life is not over, you just have to be a more responsible person, use condoms...and be open..you can lead a totally normal, healthy happy, fulfilled life!!!;-)
