The gender does not inherently impact its value or potential success.
One prospective business idea for dealsmen.com could be an online platform that connects businesses with skilled negotiators or "deal-makers" who can help them secure better deals with suppliers, vendors, or clients.
I don't see any value in it commercially. But thats just my opinion.Some domains need a little help (website, business, age, direct meaning ex. Travelplans) to aquire any value.Deals4men would be awesome.
