hi , im 20 years old male , yesterday i had sexual intercourse with a prostitute and i used a condom and i even ejaculated outside her vagina inside the condom , and i went to sleep at 11 ~11:30 PM and i woke up for no reason on 3:00 AM and i had this weird feeling in body that like theres something crawling inside of me but it disappeared a while later and after that i found out that i got several pimples on body 2 on the leg 1 on the back and on the neck and theyre similar to misquote bites , i slept with the 2 windows open and its summer in israel so there are misquotes so my question is should i be worried?
