If you are under 18, please do not post a pic of your genitals.
Have recently you been sexually active? What kinds of activity have you had, and has it been protected?
This could be a fungal infection, like yeast or jock itch, or something like dermatitis or eczema. Perhaps an allergic reaction to something.
The things in your throat aren't related to the things on your genitals. Lie bumps aren't an STD, and can be caused by a number of things - usually food-related. https://www.medicalnewstoday.com/articles/320275
So you'll need to see a doctor. I don't know where you are, and what kind of lock down you're under, but in most places, you can see a doctor if you need to. You don't need to tell your parents that you've been sexually active, just that you think you have a fungal infection or eczema or something. You can also ask them not to be in the room when you're examined at 16, and in most places, your doctor can't discuss your sexual activities with your parents at 16. Call your local Planned Parenthood or GUM Clinic or STD clinic (depending on where you are) to find out the rules for minors where you are).
Most likely, you'll be given a cream to use. Use this exactly as directed. Let us know what happens.
HI, first of all what your describing are not symptoms of any std.
