Please help me and guide me about any STD probability and corresponding tests. I am having friendship type relation with our maid. She lives with us. Never we had any intercourse, not kissing, no lick, no fingering. Only hug, touching with hands. 10 days ago, we had something different and open. I touched her vigina with my hands and meanwhile and I took my penis out. Then like a stick, I hit my penis head 3 times consecutively in between her vigina and leg joint. At that time, she was dry and her vigina was NOT wet. Apparantly no wounds, no sore, no warts were seen. Very after, I realized that any thing may go wrong. Then I moved away from there. My question is,
1. Is there any chance of contarcting any STD and if yes then which one and at which probability.
2. Also, please guide about Testing also.
