HSV 1 can possibly transfer to genitals but you have such plausible things that it would more likely be such as a cut during shaving or friction issue. I believe the normal pattern is a blister that then becomes a sore rather than a raw spot so truthfully, this does not sound like herpes. Also, initial outbreaks are typically 2 to 12 days after the exposure. However, if you are worried, your doctor can swab it to see.
