I think you should show this to a doctor right away. This is not because I'm alarmed, only that if someone is going to diagnose this, they will need to see it in full bloom. Follicultis does not typically cluster. I doubt that your squeezing caused anything in particular. I also see no role for rubbing during intercourse or any chance of scabies. If there is a dermatologist or STD clinic you can access right way, I'd go there. If not, even a walk-in clinic will do. Meantime, please leave the area alone.
Best.
