if shave all off use an electric shaver (safer, wont cut and is easier)

if trim trim back quite far but tidied up to look nice (what my gf said)

its more manly if its just really trimmed... like a military buz cut...

but if you gotta take it all off, go in the direction of hair instead of against.
you def wont get irrated if you wax, but its a more painfull option.

trimmed is fine, it's not necessarily the appearance, for me anyway. It's just a lot more pleasant to give head without a bunch of pubic hair right in your face, just use scissors or lightly run a razor over it just to trim it up. my boyfriend also said to use nosehair clippers because they're really gentle.
