44 years old Starting My Journey

Hey there, I have recently acknowledged that I have PIED and I have a wonderful girlfriend. Porn and masturbation have impacted the relationship significantly in ways that I have only recently begun to fully see and own. If I am successful we have a real chance and if I am unsuccessful we won't make it. Porn has been easy for me to stop, so far (10 days), but no masturbation has been extremely tough. I was on a meditation retreat and after day 5 I could not stop thinking about sex and had to reset. Anyways I am going to find some way to stop and maybe this community will be one way to make this vision a reality. 3 questions.
1. I am a lifetime heavy coffee drinker and recently had to quit coffee because no masturbation gave me too much energy. For years, I could not quit coffee if I tried and now it happened accidentally. I moved to one cup of black tea. I also feel I am sleeping less. Is this common?
2. What are the techniques you use to move the energy when you feel incredibly horny?
3. For those in a relationship and having sex about 1-2 times a week, do you use tantric practices or karezza?

 

Cool, I actually am taking some medicine to help with my ED in the short term with the hope that 90 days from now I will be on my way to going back to normal.
