It it worth doing a website for women when you're a man ?

Why not try?
You'll never know until you try

Plenty of women on here that would be happy to create content for you for a fee. Look around mate.

It's a good idea if you know what you are talking about and can actually provide value to these women.

who said you should create girly content "every freaking day"

let a girl handle that part, they know themselves better than we do

otherwise great idea, women are the better customers usually [for me]

It depends a lot on the niche. In some niches, women would be more than happy to have a man’s perspective so you don’t need to actually create “girly” content. And what does that even mean? Are you targeting teenage girls?

Anyway, if you’re in a niche that isn’t really one that lends itself to a male perspective, then like others have said, hire someone to write the content for you. If you’re trying to sell women tampons, for example, then get a female writer.

If you’re not willing to pay, or don’t have the finances to pay for a good writer, consider bartering. Maybe find a few writers who are interested in a byline (a link back to their site is not always necessary – some will agree to do it as long as they can get their name out there) and maybe also offer them something else in return, like help with their sites or whatever other skills you might have.

And before someone decides to slam me for this suggestion, remember that there are plenty of writers at the start of their careers who could use help setting up a website and for whom a byline on a reputable site – I’m assuming it will be reputable – would do them good.

Or, put up with the pain until your site has enough traffic to attract female writers interested in guest posting on your site without you having to hunt them down and offer your services or payment.

If you know the topic its ok :-)

I would outsource writers for some of your original content, but in terms of curating content from similar niches there isn't a problem.

Why not?
if you like to do it and you write good content for 1 niche, do it

I write for plenty of target markets, it's really about understanding the FAB's and targeting their wants and needs when you are writing. It's not hard to channel in this when you are writing for a specific niche, I agree though it you aren't confident writing for this market grab the expertise that someone who is.

Then it's a matter of whether you are being genuine with your audience or not and if you're looking to build a long-term, sustainable business or are just looking to make a quick buck.
