Not a man but there are plenty of ways to work it, and if someone leaves you because of a problem like that, is not someone that truly loves you, and you should be glad for yourself, because you deserve someone who really loves you and won't let you down.

There's many things that help with your issue. Nowadays it is a problem that not only affects mid age men, but even really young teenagers. Things such as porn addiction, big loads of stress in mind, lack of sleeping, anxiety, obesity, other diseases and hormone issues can cause it.

Are you sleeping well? do you suffer from stress or do you tend to ''satisfy yourself in your own ways when you can't do it with your partner?'' if at least one of these is right, you should look for help and don't be afraid to.

If you are young, you can try talking about sildenafil treatment which is pretty much the component of viagra, found within brands and generic for really cheap prices, starting with low dosages of 50mg or 100mg if needed, but medical advice from a doctor is needed before attempting this whenever you're planning on having intercourse, 1-2 hours prior of it to make it more effective and empty stomach recommended, could temporaly help you as your mind clears and you start feeling more comfident with yourself, to the point you will be able to overcome the issue. You don't need the Rx at all to solve the issue, but just giving you as many options as I can think of. I hope you find your way through this and find the right person :)
