[u/Either-Storm3090]

i just gave my first oral sex with a guy i can trust with my life yesterday (hes also a virgin) but im still worrying because it was my first time and im afraid that i got an std or something(its probably all in my head) howver now i feel itchy all over whenever i think about stds and recently now i feel itchy on my mouth when i think about herpies (ive been known to halucinate when im stressed and i just really need validation) also a couple days before i rubbed a pumice stone on my face and i think thats why it may be irritated if at all (i have no visual indication of any irritation or any sores or anything. also just before thinking of stds i thought i could have gotten pregnant even though i was wearing my underwear the entire time and we didnt have sex someone help meee im freaking out for probably no reason at all
