Well it started one night, my partner and I were having sex all of sudden I just lost my erection. Now everytime that we try to have sex I have a erection for 5 mins then I go limp. Im only 23 and have never had this happen to be before. Could it be my diet? I work out all the time, eat right, and take Vitamins. PLEASE HELP.
Accept your body the way it is. Do something else if you lose your erection, like satisfying your partner with your hand. Not having erection whenever you want is normal. It is the demands on yourself that is the problem.
Being afraid of not performing sexually may be the cause of your problem. Relax, have a good time together without neccessarily having an erection, do not try to force your body to perform.
If this continues to be a serious problem for you, a detailed investigation is needed to find out the causes of your problem. For example, are you taking any drugs which might have this effect?
