thank you petal 130i appreciate it.
No you can't get genital herpes from performing oral sex on someone. It's transmitted by skin-to-skin contact, it doesn't travel through your body.
Shaving easily can cause irritation such as you describe. If you've never been tested for herpes though, now's as good a time as ever to find out your herpes status. A swab/culture of symptoms and an IgG type specific blood test is what you'd want.
