Can infected ingrown hair cause swollen inguinal lymph nodes?

Hello doctor,

I have a history of skin picking, mainly ingrown hair. I have curly hair, and shaving often leads to ingrown hairs for me, especially in the pubic region. About a week ago, I was popping my ingrown hairs as usual and sometimes I go a little overboard and scratch and pick too hard. In the same time frame, I have had two sexual partners. Both I have slept with before, but one I had not had relations for a while until last week. The same guy also had sex with my best friend the same night (which I was unaware of). I also resumed having sex with my constant partner two days later. A few days had passed and the sores from my skin picking have not gone away, but instead, have ulcerated in some areas. There are probably eight or so ulcers. They scab up sometimes but the scabs do not stay attached. I am concerned now because my best friend has also noticed ulcerated areas in her genital realm and is concerned she has genital herpes. I fear that I might also, but at the same time, I am not sure whether or not it would be an sexually transmitted disease (STD) or just from where I picked at my own skin. At first, she was concerned she had gonorrhea or chlamydia. I do not have as much concern about those. There are hairs centered on all my ulcers. The only other concerning factor is that my inguinal lymph nodes are swollen and sore. I know I need to go get tested and plan on doing so tomorrow. I just wanted an opinion on what else might be going on.
