Self Improvement Made Easy

You see them advertised all the time, but do they work as they promise?

I have been interested in Tantra for two years now. Still looking for someone to help me study the subject seriously. Preferably a young lady.
I am not talking about knowing all the positions of the Kama Sutra. That's the easy part.

It's more to do with developing a deeper and more understanding relationship with your lover, looking for something more than physical pleasure and helping each other achieve it together

Can anyone recommend a course?
