Interesting comments in this post.
1st: You can herpes without it showing for a long time.
2nd: Yeast Infection is what it is more than likely. A week ago they went at it where it was posted that he entered her for about 5 mins then put on a condum for another 5 minutes (for anal was the assumption). If she doesn't clean immediately and clean well, she can get an infection very easy.
As for tonight, that was HOT! HOT! HOT! and they are still cuddling.
