What is this big bump?

I have a bump... Its not on my pen*s.
ok, example of where it is:
pen*s Bump Right Leg
|P| (B) |RL|

I am not sure what the bump is, and I am to scard to ask my mom about it.
The bump is rather larther (the size of...

a bb) and has a red dot in the middle.
If anyone has any suggestions as to what it might be, pleae let me know!!
Oh, also, it hurts when I touch it.

Have you shaved in that area lately? If so, it could be an ingrown hair. If not, then be on the lookout for it to start oozing fluid...if it does, it could be a spider bite. Other than that, I just don't know, but if it doesn't heal in a day or two, you may need to tell your mom and go to the doctor.

also: I need anwsers ASAP, that way I have ideas of what to do incase its something bad. I know I have had it for about 2-3 days.

should I try to pop it??
or leave it alone ( just in your opinion)

It could be a spot, could be an insect bite or it could be something more serious. Leave it for a couple of weeks but if it's still there get the courage to talk to your mum or doctor. Hope this helped x

thanks everyone for your help!!! it turns out it was an ingrown hair...
lol
and apparently the ingrown hair had gotten infected, and appeared purple at the tip..
thankyou all who helped me, it was greatly appreciated!!
