Hi and welcome. Well it cant be and STD cause you didnt have sex. Could be anything but when it comes to these things best to have a good checkup with your GYNO to make sure all is ok. Its always good to have a yearly physical anyway.
I've read that herpes can be there without any symptoms for years? This is why I'm all worried
I would stop googling and have your yearly checkup. It does sound like an irritation from you new tight jeans. You know your body better than us and if you has a suspicion then it most likely correct with being the jeans.
Yeah thank you! Well,I'm hoping its the jeans! I don't want having to go through it all again
