So David Deangelo used to recomend a book about Dog Training to get better at controling girls.

Then i saw this in big bang theory

I remember this girl i fucked alot.

I kept telling her she was a good girl everytime she sucked my dick.

And eveytime i told her to suck my dick she would do it without hesitsting.

What are some good stuff to use as rewards to trigger dopamine spikes?
