Fletcher is down to her final four on the show, and she said watching this season isn't always fun.
"The kissing makes me cringe. There are certain make-out scenes with the music and the up-close sound effects, and it's like, 'Oh, man, my father is watching!'" she said.
She continued, "Jordan [Rodgers] tells me he loves me. Robby [Hayes] tells me he's in love with me. Chase [McNary] tells me he wants to spend his life with me. It's all such big stuff. It's very exciting but also overwhelming."
Fletcher added that the "hardest moments" are saying goodbye to the guys she sends home.
"Those are my friends, people I care about. Even when I knew it wasn't a forever relationship, saying goodbye was horrible."
"The Bachelorette" returns Monday at 8 p.m. Eastern time on ABC.
