I know this is weird 😂

So I’m currently a sophomore in high school and I don’t really do anything with boys I usually just kiss them and I’m a virgin and havent received oral my friends are totally different tho they aren’t virgins and they don’t pressure me into doing anything they do make me want to try things but I feel as tho I should wait until I’m a senior ... but although I’m a virgin and have never received oral I have this fear that I have a std or something or that I’ll give it to someone or that I’ll get an std when I’m finally decide to lose my v card this is basically one of the main reasons that I don’t want to idk why but I’m a very paranoid person and I’m always think about my health and the worst I could get one symptom and I’ll ask my dad or my mom to take me to the doctors they have offered to get me a therapist and they have told me about something called a hypochondriac ... so um any thoughts or anything or how to make me calm down ( literally everyday I check down there to make sure there are no symptoms of an std or anything )
