^^^ typo: not levels exercises meant kegel exercises. look them up

i had the same thing for about the same time you say you've had it. it comes down to stress and performance anxiety and also porn use. you can do a lot of research on it which helped but as someone who is recovering and seeing changes this is all you have to do and i wish someone had told me thing when i was as scared and clueless 1. quit porn obviously. no exceptions. give up visual stimulation when masturbating entirely 0 exceptions. 2. cut down on masturbation if you're someone who did it often and also make sure if and when you do, you're not using too tight of a grip and you're not going dry. this conditions you away from how real sex feels 3. your issues are all in your brain. next time you know you're going to have a sexual experience, just allow yourself to fail in your head. almost expect to not be able to get it up and give yourself permission to. it takes the edge off 4. focus on what you can feel, have her initiate and take the lead while you take some deep breaths and just relax into the experience. a lot of your nerves will come from the pressure to lead and perform well so talk to your partner about her lying you down and taking the lead. take it slow 5. weak pelvic floor muscles. look up levels exercises and how improving the strength in your pelvic floor muscles can improve your erection qualities and try the exercise you'll find every day. do all of these things, and you will not have this issue anymore. it's a horrible feeling when this happens to you, i felt the same. but i wish someone had given me this advice and i didn't have to figure it all out by myself. best of luck to you man, i believe in you and your recovery

You have a case of performance anxiety which is common. You’re too much in your head. You should wait until you find true love in marriage because your heart isn’t in it

Talk to your partner to slow things down if that helps. Helps ease the stress and tension, if that does not help tell her if she can get you started. Just talk to her brother
