I don't know what is happening wit my body please help

First talk with your parents about getting a new doctor. If you cannot feel free to talk to him then he can't help you when you need to get answers like this. Just tell your mom you are uncomfortable because it is like your dad is examining you. She will get it and be more likely to let you switch.

The pimples are probably hair follicals or sweat pores that are clogged. If you pop a pimple after the white stuff or clear juice comes the blood. This is normal. I don't know if you are trimmed or shaved there but if you are, you may be iritating it when you put the razor to it. Try and keep it clean and dry. A moist crotch gets bad fast - men call it crotch rot. Not a good thing. Girls however can wear a thin pad to help soad up the excess sweat there. Pimples on your back are normal especially when sweat drips down from your hair carrying with it all the hair product to clog the pore it stops on.

If you have been sexual in the past and unprotected, be sure it isn't tied to that. This is the reason girls should carry condoms and not always rely on the guy to suite up at the last minute. If you have one, there is no excuse for him not to wear it.

Try Googling this FOLLICULITIS.... It's a follicul infection that can come from sports(a lot of sweating, so it's kind of like a jock itch if it's on the vagina) or shaving. Have you ever seen a guys face that shaves and sometimes it's really bumpy, it's more than likely folliculitis because they cut themselves which opens up a way for infection to start, same thing with some women who shave their legs. There are some treatments for it (meds, creams, home-remedies such as vinegar and water to soak the area in) But you should go to a doctor and let them see so you can get the right diagnosis. One question, are they painful and a little itchy, just because they are doesn't make it an STD those are some symptoms of folliculitis. I got it in 6th grade when I began playing sports and I would get bumps on my back too because of the sweat from my hair and my back sweats a lot. So I finally went to the doc like 4 years later (painful 4 years because it began to get worse) and my doc told me it was folliculitis and he prescribed meds and a cream and it worked for a little while but it came back and he said it's because I play sports. So then he said that if I wanted it to go away then I would have to stop playing sports. So I've decided to bear through it for another 1-5 years (depends on if I play in college). But lately I haven't had an outbreak so maybe I've grown out of it (it's possible, my doc said so).... so I hope I've kind of helped... and keep us updated on whether you find your answer.
