Going on a day ago I went to a girl house and we were playing around for a bit she got aggressive and grabbed my nuts, 10 mins later we had sex but it wasn’t more than 1-2 mins due to my inactivity of masterbating for 2 months, today I woke up and I just feel uncertain if I had caught an STI, there is no burning, there’s a little itching but i think it’s because I hadn’t washed my area properly, please help I am hoping for the best and I am hoping that I will be ok. Is it just my anxiety kicking hard or do I have something. I’m 17
