Many people truly do not know what masculine is, thus we have misconceptions that being masculine means you're not comfortable in the kitchen, can't iron or are very good at motor mechanics.
Being masculine is simply not being afraid of or ashamed of your testosterone. Being able to iron has absolutely nothing to do with it. Actually, if you're to be a player or bachelor then it'd be a very good idea to learn how to iron as no respectable man will be seen in a creased suit.
Only if you're not comfortable enough in your masculinity as to be afraid to do traditionally feminine chores then you have a problem.
