Yoga should be learned with a teacher. That would be ideal. If there is no teacher nearby, you can also get along by studying from books. There are also instructional DVDs and lots of U-Tube videos on the subject.
I also find studying online very helpful. There are already numerous options online today; just search and choose something that suits you.
What strikes me is the fact that in India, the country of yoga's origin, there are significantly more male yoga masters, while in the Western world, it is clearly women who make up the yoga teachers.
So, men: come on!
