Could you have hpv? Had a friend when younger mention cuts and she was diagnosed with hpv. Most are harmless but you should get the cuts checked by midwife. For time being try not to infect it so you probably shouldn't be intimate until they heal
They weren't there before I had sex, when the sex started a felt it pulling my skin some. And so I stopped then I felt like bruised and saw the little lines.
I would get it checked out and start some perineal massage so it can stretch and hopefully not tear.
