STD (SEXUAL TRANSMITTED DISEASE)

my friend who works as inn recipient also as take care prostitute there, suddenly called me to bring him to hospital. I told him why? because doctor asked him to go and in shy way, he say he got something grow in his balls. whattt???? 

I can't bring him to hospital as i work. I called him again on the night next day whether he already met doctor. He said he already met but he didn't explain further..

I think he got this STD. didnt use condom during sex. i google at the image..the growth things is scary...euuuuuwwww...I lose my sex appetite watch those things...maybe i shouldn't sleep with prostitute again..but i use condom :D
