Help, a large red bump on my partner's s*****m?

Question

what can it be? he does not have an STD or anything! what is this? what can I do? the s*x is very uncomfortable.

Answer 1

I think it's probably a clown nose.  Does it honk when you squeeze it?

Answer 2

What Excel M said, only it is commonly refered to as a "Boil".

He could wait for his own body to take care of it or see a doctor to have it lanced. Don't just pop it all on your own, it could get infected and then it would get worse! (Not to mention it will hurt like all h**l!)  Placing a warm wash cloth on it will draw the "contents" to the surface and speed healing, this should be done once or twice a day until the desired results are achieved.

Answer 3

Sounds like a blocked hair follicle  

Answer 4

BITE IT OFF!
