Hello David, sorry it does look like it, especially being under the foreskin fold part. My partner has it and looks similar (I have the oral HSV2 and passed them to him). It does seem like a long time since you had sexual relations, but it can lay dormant in the body until your immune system is low (for example being on antibiotics) so go get swabbed. You need to know for sure.
My partner only got his first breakout after he had had surgery and was on antibiotics and then got thrush. quickly followed by breakout. Did you get any flu symptoms?
Not necessarily. Lesions don't usually form on the scrotum. I would get them swabbed
