My girlfriend and i had sex for the first time the other day. It was brief but new. I only was inside for about 5 minutes and she felt discomfort. I'm not sure if i was causing the discomfort or maybe she had something, She did have these sores on her outer lips. I did not ask what they were. Anyway, is there any quick fix for this? i am afraid to tell her about her little problem but i don't want any more sex to be not fun. Thank you for your help!
Hi i'm sorry to hear that. 
. But you should never be afraid to ask
questions when it comes to your health & life. But she felt
discomfort than something it wrong. When I had my outbreak
I had my boyfriend look & they were little sores but I also felt
them cause just washing myself Down there wasn't easy either.
My doctor had given me valtrex & a cream to num it down there
the out break was so bad when I had my first major outbreak
Last year. I had a refill so as soon the sores started to bother me I
didn't have sex with him started back on the valtrex until the sores
went away. My advice you should both go get checked. She may
Not even know what may be going on. If this is the case. If you
love her don't make her feel a shame. Believe it people you
Already know have it they just don't talk about it. Many don't know
they have it until an outbreak happens. My advice go with her to
the doctor let her know you have her back. If it's HSV. The doctor
will discuss whatever it is & the options. You need to get checked
as well for your own well beings. If it is indeed the HSV just know
there's no cure but there is treatment. It's not a death sentence either.
if you support each you will be just fine. Learning the systems also help
lots of things can trigger it so try not to stress do it together.
Good luck

If it was her first time also then it would obviously be uncomfortable. The sores on her vagina may not be herpes though... especially if you have only had sex the once?... Unless she had sex before, or someone has given her oral that has coldsores.
Sorry to get personal but if she shaves down there could they me shaving cuts? Anyway best to discuss it with her, and both go to the doctor x All the best.
You shouldn't be having sex if sores appear to be down there. She needs to be checked out by a doctor and get proper treatment if need be. The same applies to you.
