What Causes A Bump On The Labia?

I have a bump on my labia. I haven t had sex in over a month & prior to my most recent partner, it was two years since having sex. I made sure we used a condom every time. I m really hoping this singular bump that feels like an insect bite is not a herpe bump. It s only one, it feels like a pinch when pressed against. There s no puss & it s not crusting over like most discriptions of herpes. Any idea what else this could be? I few years back I was told I have lgsil hpv, but my partner had warts & I didn t. It mentally tore me up. I don t think I can handle being told I have herpes too.
