Hi, so i was relieving some stress by masturbating, and i had to go somewhere in a few minutes. And i was rash about it, and a littletense when i started too jerk off. When it kind of hurted..? 2 days later i releasized a small red or purple, sort of looking like a bruise. And now i can t maturbate, cause it hurts to even touch it. What should i do?
