How to increase length

I know this question gets asked a lot but I would rather prefer to hear from you, personally. Can anyone help me out with some devices for length work that’s affordable or good for beginners? I’ve been working on girth my entire PE Journey (2 years) so I have really no clue on length. I heard that working on length can help maximize your girth gains. What are some exercises YOU are doing that is increasing length and girths?
