tmi if you hadn't guessed already

So I have this sort of opening or something on my underwear line, right where my leg starts. I thought it was an ingrown hair at first, but it's not. It's sort of leaky, with a transparent discharge along with a bit of blood. I've had it for awhile now and it doesn't hurt. It looks a bit bruised too. I've never had sex, so I doubt it could be an STI or STD, though I know sex isn't the only way to get those. Any ideas? 😅 sorry this was so long
