Hmm, idk really.

Because they also call it girlfriend instead of womanfriend? 🤷

My first impression is because manfriend is more of a husband thing...
Whereas boyfriend is the early stages of a relationship prior to marriage...

Maybe ... I dunno 🤔

I guess for the same reason they don't call it womanfriend instead of girlfriend.

How about just friend if that's all he is or more serious might be significant other?

Right, mature relationships

and won't a girlfriend...get you on a list somewhere?

Why not womanfriend instead of girlfriend?

Have fun tilting at those! 😉🍿

Association of romance with the young at heart.

because it's a misuse of the word

there's not supposed to be a romantic connotation with the word boyfriend

but dudes are too scared to be called gay to say they have boyfriends when that is EXACTLY what they have!!
