I forgot to mention about an aspect of tantra that is called dark tantra. It is about allowing ourselves to explore our darkest fantasies to be able to transform them in deeper satisfaction. Our fantasies and sexual desires becomes a threat to follow to become a more complete person.
What I understood is intentions and attitude is the most important thing with everything, not what I do apparently.
Otherwise said : I can be gentle and nice in actions but inside is pure frustration or I can be fucking hard in all kinds of combinations with the highest intentions of conquering my whole being.
