Based on some of these descriptions including her chiseled jaw, her enlarged clit (lol) and her muscle tone I'm almost convinced that Karinna might be injecting steroids/hormones. They're incredibly popular with Brazilian/Latina fitness women - Winstrol is their favourite! Head this from a female prossie from Brazil also into fitness, and it's just generally well known! That stuff tends to send a woman's sex drive sky high, too... which automatically equals a sensational punt...! Of course, not a knock on her, based on what I know if used responsibly, these drugs are perfectly safe...!
