Slut Shaming Advice 😑

There's a huge group of foreign students at my college.  Many are from Italy, and they all talk to one another/are connected somehow.  They're also very popular around campus.  One student is my coworker and I ended up giving him a blowjob one night. It was a one time thing, but weeks later, when hooking up with a guy from the same country and social circle, the guy mentioned that he heard from a random Italian student that I hooked up with my coworker. Apparently they all talk to each other anything. My friends are telling me that I need to take it easy with hooking up with any Italian students because I'll get a "reputation".  Is it really right for me to have to sustain my sexual desires because of the opinions that people I don't even know might form about me?
