THanks for the info. No there was no genital to genital contact and I am not feeling any side effects or anything.. though it was just last night. I was mostly worried about where here hand had been since she had been touching herself before touching me.
That is not true. Not in the way you explained it. You are not at risk for contracting an std from a hand job. Did your penis touch her genitals at all? Even so, unless you were near her vaginal opening and got some of her fluid in your urethra (which is likely to only happen with penetration), then you were still at no risk for chlamydia, gonorrhea, syphilis, HIV, hepatitis.
You would know if you have crabs. You would feel like something is crawling all over you. And herpes is a possibility but very low if she didn't have any visible blisters. If you don't get any blisters in the next couple of weeks, then I would not worry.
Well, you cant say for sure whether there's anything to worry about unless you're having any side effects or anything yet. Are you having any?
