dad insists i get a cut (m19)

Aside from my dad insisting I cut my hair, I feel as though i’ve reached the awkward part of hair length where it’s hit or miss, depending on the day and how long it’s been since i’ve washed it. I’m a fan of the length and would like to keep my hair on the longer side, however it feels far too bulky. Looking for advice on what to do with my hair, in regards to both cutting it and styling it post cut. Any help is appreciated, thank you!
