My problem is related to low sex drive and performance anxiety. since last 3 months i am literally feeling panic at the time of sex. Earlier i was sexually very active for two years. In routine i m having good erections when we go out somewhere but 8 home at the time of sex i m like zero feeling. I m having flu from last 3 months even after taking so many medicines i improved in terms of stamina but my one side nose remains blocked all the time. I hv taken sildenafil 50mg once in month in last 3 months but i m feeling so disappointed from myself not being able to do it naturally, i love my wife so much i cant see her unsatisfied. Plz help me.
