Boyfriends friends 😷😦😡

Okay, so they shouldn't bother me but a couple of them irritate me like right now my boyfriends and I have been together for 7 months. Two of his friends I haven't met but they feel the need to talk the most shit!! We had sex last night. And I'm guessing he told them which is no issue to me. But his one friend said "oh be carful syphilis is going around". Like one he's the only guy I've been with raw. Idk why it bothers me but it does it made me feel like shit. Idk why but it does now I'm pissed cuz I do everything in my power I can to be protected and clean and safe and this stupid motherfuckers crack jokes like I'm the dirties bitch on the planet. Like yeah I might not be good enough for him or make him as happy as another bitch could but I'm doing my best to make sure that he's happy fed and idk it just pissed me off. I don't have any friends to talk to so I guess I'm gonna leave this here
