Now that you are married, avoid all masturbation and use of pornography and allow your sexual tension to increase. Be sure to include plenty of foreplay when sexually involved. If this problem continues, allow your wife to give you a handjob three or more times per week even if you do not ejaculate. Limit these sessions to a half hour or so. By this, you will get away from self-stimulation which is different than being sexually involved with your wife.
