I'm sure there is a substantial audience for male feet, and that you will get a lot of interest. In that respect, go for it - it's obviously something you want to do. 🙂
Youtube itself, though, is full of buttpipes. If you don't have a thick skin, you might want to disable comments and/or ratings. Because haters shalt hate. Also be sure to label your videos correctly. If you label it as general foot fetish, you'll get a lot of people going there under the impression it's female, and then getting disappointed and angry because they fapped to male feet. Be sure to label it as male feet, and 90% of the non-interested parties won't even come near.
I hope this helped. As [famous personality] said, "if your actions reflect not your own, but the wishes of those around you, so too shall your will belong to others."
