Little update: so i have been edging with a focus on that spot. I must say it has been hit or miss. I find that some times i can edge while rubbing there no problem however if i put pressure there just right by pressing into with my finger bam i go off even if i wasnt particularly close to the ponr. Anyways the edging seems to have paid off as i had sex the other day probably 25 mins or so several different positions including some max effort pounding at the end and didnt even cum. Didnt get to finish as i got a little carried away with the thrusting and hit her cervix which stopped the sex pretty much cold but i didnt care just happy to have had good control on climaxing.
