For The Past 2 Days Me And My Boyfriend Have

For the past 2 days me and my boyfriend have been having sex and today I threw up 4 times, after sex it feels like my stomach is in pain paradise!!! For at least 2 hours . My boyfriend also says it feels like something is scraping.His penis during sex he has little paper cut looking cuts on his penis . By the way I have a hymen in my belly button so Idk if he could possibly be hitting that . I wonder if I'm not wet enough. I used to get Wet all the time . And now very little I'm 21 years old and he is too .
