Ok, so I started going down on my GF about a month ago, and ever since I guess she has had this itch. It started happening like the next day after. She thought she had a yeast infection, and we didnt do anything for like a week and she took some pills/cream etc. Itch went away. So we go back to doing what we do and she gets the itch again and now she says its really unbearable. She wants me to get tested for STD. But the thing is she is the first girl ive went down on/kissed. WTF?
