I had sex for 3 sec cause we didn't have condoms so we stopped and we were virgin that time. can you get hiv or aids from it? t

Sadly yes: Unprotected sex is one of prime risk factors for pregnancy and sexually transmitted diseases/infections, including hiv/aids. That's why it's imperative for guys to wrap it up & wear a condom each & every time, regardless of whether your partner is on hormonal contraception or not (b/c pills don't prevent stds).

HIV is Hard To Get: Now. Here are the real facts: unprotected insertion of an erect penis into the vagina or anus can lead to stds. Even for just a few seconds. It can lead to pregnancy in the vagina if the female is ovulating. Now if both sexual partners are disease free and have not ever participated in any activity to get HIV they cannot get it from nowhere. Thus your scenario is one that you cannot get HIV from.
