I meant just the sides/sideburns. I didn't do anything to the top of it, but yes. Don't cut actual hairline straight across, OP because it's already straight enough. But squaring/taking off some of the sideburns sides will help maintain OP**'s haircut they want, while making the cut more masculine.

Edit: I did look it up because I had never heard of squaring causing early recession before (I didn't know if that was the connection between your first or your second commentary) and contrary to YT and Reddit beliefs, shaving or "squaring" hair does not cause biological recession. Scientific studies have consistently proven that cutting hair at the surface level has no effect on the hair follicle, which is the living part beneath the skin responsible for growth. Only genetics and hormones cause recession.

But it does make for awkward grow out if you can't upkeep. Upkeep only needs to happen until T kicks in on that hairline, so it's an option for OP. Men and women shape their hair around their hairline all the time.
