Hi and welcome to Healthcare magic.Thank you for the query.
It doesnt sound like skin cacer but I think that it should be surgically removed since it is in shaving area and it may be problematic in future. Skin cancers cause some other symptoms and signs,but noone can be 100% without biopsy
report. So it should be removed under local anasthesia and then sent to patohystologic analysis.
Wish you good heaIth. Regards
