Your list is great! Ideas:
[name_m]Oskar[/name_m]
[name_m]Jakob[/name_m]
[name_m]Marek[/name_m]
[name_m]Patryk[/name_m]
I do love [name_m]Konrad[/name_m]. I knew a [name_m]Conrad[/name_m] who was adorable so i have that positive association with the name. [name_m]Konrad[/name_m] has very strong consonants and I think it’s really hansome.
