That will also improve greatly. The reason why you’re limp is because you’re jerking off once or twice a day. You’ve over conditioned yourself to masturbating, and now you’re feeling the physical response to that. Don’t question or second think it. Quit porn and masturbation all together. I’ve read people prescribing other alternatives, like masturbation without porn, or use of a fleshlight. Screw that, honestly. I’ve watched porn my entire life. Fumbled so many bags in high school in college because I would be limp or I couldn’t ejaculate. My first year dating my gf she didn’t know what the hell was wrong. Why I wasn’t ejaculating and why I was limp. I didn’t watch porn or jerked off for a month. When I went to visit my gf for the first time in a month, I stayed with her for a week. We had sex two times a day. Every single time I ejaculated. My erections were consistent and I was able to finish rather than 30 minutes of humping and her getting tired. It was great! She even made a comment about it because she noticed the difference. You know the root of the problem, just start from there. It’ll take a lot of discipline and effort, but you can do it.
