I’m a heterosexual male who recently had sex with a random girl. We had protected vaginal intercourse only. Halfway though it, while the condom was still on, i realized that there was a big chunk of the condom hanging off the tip of the penis. (It was the as though condom got elongated when we were having sex). We carried on having sex with part of the condom hanging off the top of my penis as the condom didn’t slip / come off. Am I at risk to any STDs from this encounter?
