your voice has a natural reverb anyway so technically you do..... but if you dont use reverb then your stupid... EVERYBODY uses reverb, be pop singers, rock singers, rappers, operah singers... reverb is used on everything.

even on your beats, your hi-hats, snares, kicks, piano, guitar, organ, horn so on n so forth, all get reverbed.... your vocals NEED reverbing, but not alot... but if you dont use reverb you must use echoe, and that just proves your stupidity with editing vocals
