I'm a 29 m, and i'm still a virgin. Its hard being on

First let me say, way to go! Waiting until you are married is the right thing to do. I wish I had. You will have something so special to share with your wife. (Provided she is a virgin too) I have been married for 25 years, and when we were first married, the thought that I had sex prior to getting married was upsetting to my wife. (She was a virgin) Anyway, onto your question about performance once you get married. I am assuming that masturbation is not of limits for you. I recommend that when you masturbate, take your time! Work up to the point just before you get the urge to ejaculate and stop! By clenching / tightening your anus muscles it will prevent the flow of sperm. Wait a couple of minutes and repeat, as long as you are able. This will lengthen the time it takes to reach full climax when you eventually have sex on your wedding night. If masturbation is off limits also, which is a very noble thing in the scope of waiting until you are married, do not worry about performing during sex. Let nature take its course. If your future wife is also a virgin, you will both be in uncharted territory. It's about the act of making love, not how long you can last. If your focus is completely on satisfying and making your wife the object of pleasure and your motives are true, you will be just fine. I hope this helps. I'm sure, I know you will be just fine. In 25 years you will look back to this time of your life and ask, what was all the fuss about. I wish you the very best in your quest to be all you can be to the wife I know is out there wait on you also.
