I've realized I am a Dominant in the internet, and as my work I enjoy being the boss, I like to be in charge, even way before in school I was most of the time the leader.
Technicalities... Hmmm. Try to check out kink.com they have this episode on basic rope bondage and basic cbt, that is where i started. In terms of orgasm denial etc most were practice with a submissive during play time.
And of course I can't thank enough my Dom friend who is helping me out right now, teaching me the ropes, he even let me tie him up for practice. I think it helps alot learning from a another Dom/Domme.
Yes I think there is effect on being trained to be a leader, with girl scout and military training.
A lot of thought about psychological, in my opinion its very important.
