Google, male deer exercise, kegel exercise and Satkriya.  You may also google anal peripheral prostate massage; ( this is a powerful exercises; Stronger than kegel exercise.) you should learn abdominal breathing for 10 minutes twice a day. By slow breathing you can control your erection for a loner time. Slow, deep and even breathing will give you better sexual stamina. you will have to do these exercises for a longer period. Make it a part of your life. Kundalini yoga is meant for monks/sanyasi who need to control their sexual urge. This will work for enhancing your sexual stamina also. Learn from an expert. wish you best of luck.
