hey guys, just need to get something off my chest. okay so last year i got oral sex from a girl and thought i had an std it turns out i didnt, but i fell into a depressive/paranoid state where i stoped leaving the house and i would just sit in my room and cry. i finally got over it this has happend to me with alot of other things where i thought i had more of diseases or conditions for example i thought i had testicula cancer, i thought i had brain cancer , i thought i was bi sexual, i thought i had a weak bladder, i thought i was balding. 

back to where i started, i have been offered sexual opitunities from girls lately and have turned them down because im to scared ill catch something, someone please help me get over my fears. btw, i am a 14 year old male.
