Private parts

Is it normal that i have pimples in my private parts like below testicles, on the side between testicles and thighs as well as between my bums next to my ass-hole? I am a bisexual guy but always protect myself when having sex. And that i love holding a big cock and love sucking it but i just don't like that fluid (semen) enter my mouth and am also afraid that i might suck a positive person since most gays are not trust worthy. Is in normal?
