Frenulum: Does Frenuloplasty Make It Less Sensitive?

Hey guys, I just noticed that my frenulum might b too short n i'm gonna c a doctor about it in 2 days

but before that, i'm just wondering whether lengthening the frenulum alters its sensitivity

apparently its really sensitive right now that I can't last long when I have sex, im guessing thats b/c the frenulum is kinda short n when da foreskin retracts, the frenulum sits right on the edge of da head, thus its always making full contact (just guessing, not sure if this is normal)

so put aside whether I have frenulum breve or not, how does it change ur sex life if frenuloplasty is done? Given that I am actually still capable of having sex now

thanks for any comments!
