I've been having a open wound on my scotrum for two weeks now and it hasn't fully healed. It sweats and tends to leave a foul odor when I don't wash it for a while. I also feel a burning/itching sensation from the wound every time I move. But I've never experienced any bleeding. The only stuff I've been experiencing are burning/itching on testicles and foul odor from a puss filled swear it produces. I don't know how to treat it. The first wound appeared from my attempt to shave my testicles with a shaving razor (I know, I realized how stupid that was and will never do it again). Are there any treatments or medications I can do to completely heal these wounds on my scotrum and put a complete end to the burning sensation? Thank you.

I also apply Vaseline on my testicles to ease the pain a little bit. But it only works for a short period time.
