I believe my past porn usage has led to me reaching climax VERY quickly the minute any sort of arousing behavior starts. I would masturbate with the intention of cumming asap and conditioned my body to go straight from getting a boner to orgasm. This is probably what caused me to develop premature ejac from simple things like making out with my girl. What I want to know is, how do I retain my arousal in order to tolerate the pleasure of intimacy and sex without automatically going to orgasm? Some of the arousal guides I've seen on other sites suggest edging with porn, but I don't want to use it because of the ED side effects. I can edge for over 25 minutes if it's without any sort of material or fantasy. So the problem is the arousal building up way too quickly. How do I overcome this? I'm guessing I just have to force my brain into not letting my attraction to my girl overpower me into cumming fast? Please advise.....
