Please, don't ever use a pimple popper on your genitals. It's not meant for the area, and if you have some kind of bacteria or virus, breaking open the spots can make it spread, and it makes it harder for the doctors to identify what they are.
Plus, I imagine it hurts.
It could be warts. HPV, human papillomavirus, is the virus that causes warts any where on your body. There are over 100 strains of it, but the kind that give you genital warts only affect the genitals. The strains that affect your feet - Plantar warts - only affect your feet, etc.
Since you have so many, it could be warts. It could also be molluscum contagiosum. That wouldn't be from your activity in 2019, but you can get that from a gym, if you've been in one in the last several months.
You need to get a doctor to see this. There are always several possibilities when it's bumps, and no one can diagnose them online. Let us know what happens.
