any real men worth his pride will feel ashamed when they compare
their bed skills to porn stars. We must learn from the best, and
porn stars are out tutors......otherwise, how can we improve and
upgrade?! 
i learn from the videos at my own pace, own timing, and my
instructors, although virtual, are from all over the world,
including USA, Japan, Africa, Malaysia, Korea, Brazil, Germany and
Russia.
Like it or not, the best lovers in this world are those who can
open their mouth and ask their women how to be a better lover.
I don't think men are capable of learning or finding out how
to satisfy a woman appropriately without hint, advice, and
guidance from women.
I won't be surprised if all your so-called instructors,
pornstars, masters, learnt it all from women.
Cos without women, men are only capable of satisfying themselves
best.
