Hi Sir, Welcome to Health Care Magic I can certainly understand your concern about your sexual problem, this could be possible in newly married couple due to apprehension, so be relaxed and share your mutual thoughts. test your erection by yourself by NPT ie nocturnal penile tumescence, in which erections occur in sleep during early morning, which can rule out any problem with erection I can suggest you master and johnson technique, in which your wife has to squeeze your penis forwards just before losing erection, practice this regularly, if there is no improvement , you can start on sildenafil, to improve erection by increasing NO production post your further questions if any thank you
