No, some sexually transmitted diseases (STDs), also commonly referred to as sexually transmitted infections (STIs), are not transmitted consistently every time an infected person has sex with someone who is not infected.

Can you get STD from being around someone?

A couple cant create an STD from nothing — they have to get spread from one person to another. But just because someone hasnt had any genital-to-genital contact with anyone else doesnt necessarily mean they dont have an STD.
