help pls

I like REALLY want to have sex with 2 dudes that go to my school but I'm too scared to openly admit it to either of them. Plus I'm afraid that if I do openly say it, they'll reject me or the whole school will find out that I had sex with them. What should I do?? Should I just stop being scared and go for it?? The worse he can say is no, right?? Who really cares what people think?? Idk,, I'm so confused
