I have only had one sexual partner - my DH and DH has only ever had one sexual partner.
However, last night I broke out in sores around the opening to my vagina.
I can hardly move, I can't pee without being in the bath.
It's Herpes that I caught from DHs mouth 
The thing is we're desperately ttc ASAP (medical reasons make sooner better). My fertile period' started today.
The GP has given me some numbing gel but it still hurts.
I'm dreading it (so is DH as he doesn't like to hurt me), but think I will still ttc.
