Genital warts should not feel like a scab, that sounds more like herpes to me. Also all warts look different so you can't diagnose yourself by comparing to pictures online.
You had unprotected sex, so you had a high risk encounter, although it could be many things not STD related. The only way to know is to get checked by a professional. If it is warts, then the longer you leave it, the harder they will be to treat.
i looked up genital warts and these bumps kinda resemble those on the pictures
