should i admit to my friends that i masterbate?

I’m 16 years old and whenever someone brings up masterbation asking if anyone’s done it, all my friends say things like ‘no ofc not that’s gross’ and i usually say the same thing because i’m embarrassed. But i’ve been masterbating for a few years now and i dont know if I should admit it to my friends because I’m afraid if I do they’ll think I’m gross. What do I do?
