Skin itching below my right testicle

I have this itching that's been bothering me for almost 2 weeks now, below my right testicle and moving backwards from below the testicle and backwards.

i have tried the following:

1- using dettol ( diluting it with water )
2- using Itchguard ( cream )
3- iodine
4- using protex anti-bacterial soap

how the backward itching has disappeared
but the itching below the right testicle still remains, i have no speicific noticeable effect, the skin becomes reddish with itching of course but apart from that the color is normal

what should be done?
or what is the case and what should i do ?

i just wanted to add, that the itching isn't so frequent or non-stopping it does calm down but gets back to me along the day its not so painful or annoying but having it for almost two weeks is becoming annoying !
